That rope wrench of Eric's may give just enough resistance to stop the creeping in the ZZ for SRT. I know me in DRT is half the weight of SRT, but the MRS causes more flattening along a rope (especially one that flattens easily), than SRT. So maybe Scandere is even more susceptible to slipping in DRT with no other conjunctive rope devices attached to the ZZ.
Since the bollard (slic pin) on the Rope Wrench is effectively flat any construction arborist line will flatten somewhat. With the exception of twisted steel cable. I still maintain until proven otherwise that Tachyon keeps the best roundness under load, the third inner core construction was designed for that purpose. Some flattening improves performance on the Rope Wrench and Rope Runner devices because of the increased surface contact. I’ve found that the Rope Runner bird releases hard on Tachyon because of the reduced friction contact area. Once the Runner bird bollard is broken in Tachyon runs better on it. Tachyon is fairly bouncy so it’s not preferred by most climbers for SRT.
The rope surface is fairly stable after initial break-in use takes the brand new slippery shine off. If a climber uses cambium protection the degradation of the rope surface is going to be very slow. Work hardening and UV is going to be the limiter for rope lifespan. If a climber doesn’t use cambium protection for MRS/DdRT the abrasion effects on the cover are significant and greatly shorten the life of the rope. You may not detect it after a few climbs but over weeks and months there is significant damage to the cover.
Yes, I'm wanting to actually rid my self of it, the creeping happens too often. Would you have a length of at least 150ft of a decent rope like XTC or Blue Moon or something of the sort, that we could do a swap? Thanks.
How long is the scandere? Does it have the sewn eye? I’ve got 150’ of blue moon with tight eye splice, it is used, but I could sell/trade with good conscience. Blue moon I’ve found works great for DDRT, and SRT. Mechanicals and/or hitch based systems. Natural crotch, or friction rings…. It is damn good rope.
It is more than 160ft, about 162ft, I'll check the exact length later. Yes, a sewn eye, (but it's not as tight as I'd like it, the sewn eye seems to have stretched since it was new) It was originally 200ft, neon yellow, I ordered it from ArbSession. Your Blue Moon being used is ok, at least it'll be "broken in". Are you willing to part with any ropes that are slightly bigger diameter than BM? 11.7 or 11.8?
Everything I’ve got new or used is 11.7 varieties, or a used Samson arbormaster 16strand which is 1/2”.
Oh, I see. Is the Arbormaster a true half inch(12.7) or right at 12mm, or 12.5mm? Thanks. Well, I guess your BM sounds good. Do you notice much flattening with the BM?
Too bad to hear that Re Scandere, had thought it was Yale's "bigger type of Mercury", obviously BiFrost is their 11mm, newer/marketing "answer" to Samson's amazing Mercury!!Hi, I'm new to this forum, signed minutes ago. I'm looking for some help in finding a rope that has a minimum of 32 (preferably 48 strand) braid strands with a minimum of 3 carrier strands (in 32 strand), that has a very tight cover braid. Similar to this Beal Access rope:
BEAL ACCESS 11MM WITH UNICORE
The standard in access ropes for maximum security in all situations. The Access with UniCore brings a new level of security to your work or rescue operations. UniCore process bonds the sheath and core without affecting the ropes suppleness or handling. Sheath slippage is virtually eliminated...libertymountain.com
The two problems I have with rope is it's too stretchy and and too small diameter. I know this is a rock climbing rope, but it's the only rope I have found that has a high strand/carrier count, yet also stays very round with high side pressure, and is moderately stretchy.
I recently purchased the Yale Scandere, which flattens severely, and is too stretchy, which I couldn't fully know until I used it.
In lieu of finding the rope I'm looking for, I'm thinking of petitioning a local rope manufacturer to make this ideal rope: 12mm, 48 strand very tight nylon cover braid (nylon is abrasion resistant enough, but nylon is more porous than polyester which would increase the grip), with a balance of nylon and and polyester core, (to get the ideal bulk with less weight, but still keeping it a static rope).
)
Interesting, I've never looked very hard at Mercury. Noticed in a tech spec that the cover fiber is HTP (high tenacity polyester), that could account in part for the hard/tight feel and add to the overall strength rating. Normally you'd think that a kernmantle is core strength only but the HTP cover is likely adding strength.Too bad to hear that Re Scandere, had thought it was Yale's "bigger type of Mercury", obviously BiFrost is their 11mm, newer/marketing "answer" to Samson's amazing Mercury!!
How, precisely, are you noting this 'elasticity/bounce'? I ask because I hear this complaint enough that, when swapping from Blue Moon (1.4%) last year (wow, like 54-55wks ago now) to Mercury (3.5%), I figured I'd feel some but if anything I'd instinctively tell you Mercury was a MORE static rope, because I've never noted an iota of stretch in it but, in the hand, it's WAY firmer than Blue Moon, stuff is incredibly 'tight' which is probably why you can't officially splice it (and doing so w/ Drenaline instructions works but isn't worth it IMO, took me nearly 2hrs each time
In EVERY other arena, sub-5% rope is ALL considered static, I mean when I upgraded to Mercury it should've(DID) given me an extra 2.1% stretch, so 1.1' of stretch on a 50' line if&when I'm hitting it with 10%ABS which is 850lbs on Merc., from tests I've seen you can barely get past double your bodyweight climbing (unless you were intentionally bouncing I guess) which means the stretch should be virtually imperceptible, nevermind that - as soon as you put your hitch&asccenders onto it - you've already achieved the overwhelming majority of the flex/elongation right then&there..
But yeah Mercury is a freak, still have an un-used 150' but once that's gone I'll be getting a blue hank, I do prefer the hand-feel of an 11.7mm+ rope but it's not worth the extra weight IMO and it's unnecessary for good ABS ( though IMO ABS is a bit of a misnomer, as it's only concerned with static strength and all our big concerns are Re dynamic hits...that's why I'm more inclined to go "bouncy" on my climbline than bullropes, though I will mention I use Polydyne 1/2 and 5/8 (3.5%) and would've gone higher with Atlas if I'd known enough about Sterling to trust them when I was making that buy!)
The biggest surprise to me, beyond the price given the specs, is how hard/resilient that cover is, they don't even publish thread count AFAIK but it's very high, and VERY tight, probably the definition of 'hand', but am still very surprised that the one I use for bullrope is not showing cover defects!! In fact it takes bark-friction better than the coats/jackets on my polydyne!!
Re the textiles, I'd always seen it a different way...nylon for the core, to guarantee your 'lifeline' is the safer innerds, and the lighter, slicker poly outer jacket, because I'd thought that your hitch was WAY more about relative diameters & how you tie it, not surface-friction per se..... Wow now that I think of it my 'mercury flipline' is the ONLY merc I have that shows 1/2 its age, and its sole 'defect' is significant color-fade & darkening (because it's my primary/daily flipline, and I use this 15'+ flipline hard)`
Hope you're happy with whatever you choose, oh and if I didn't already mention it, Mercury is very very cheap for some reason, I don't get that (think it's the strongest 11.0mm on the market, if not it's the top 2 or 3), they just did a whole new approach to developing this rope it is amazing I wish I had other kerns so I knew if others were this good (they aren't on-paper/specs)
Just curious can one purchase the XTC 16 strand in exactly 12mm? Isn't the common XTC Fire 16strand right around a true half inch (12.7mm or is it 12.5mm?)
But, the Mercury is only 11mm, under the diameter of an ideal rope of 12mm. Also, it's not a true 32 braid, they're counting the extra carrier strand as another braid strand, when it essentially doesn't really add the benefit of another braid strand, nor the increase of surface area.Too bad to hear that Re Scandere, had thought it was Yale's "bigger type of Mercury", obviously BiFrost is their 11mm, newer/marketing "answer" to Samson's amazing Mercury!!

Well, lol, I'm not surprised at the response. It seems most people aren't as discerning as they should be about most things. It seems some of it, if not most, is due to complacency. Things would be better designed and governed in this world, if only more people were more discerning.
Its a 1/2" line. Closer to 13mm. Especially once it gets worn a little. Nice and grippy.
Yes, I ordered a 5ft sample from Rope.com, and I was hoping it would run easily in the ZZ, but being 12.7mm, it's a bit wide to run in the ZZ. I thought maybe Yale had a 12mm version of the XTC. It's less grippy in the hands than most other famous tree climbing ropes, when unused. But, when it's abraded by used, it's more grippy than most, is nice hear. I do have the Edelrid Direction Up 13mm, but it's more like 12.5. And, it's a bit big, to easily flow through the ZZ.
I don't think I've ever tried Adrenaline.
