hey guys and gals, i was wondering if any of you use this promaster 3 strand rigging line by samson, we are looking for an affordable but rugged rigging line we can buy at bulk and nothing is more affordable than 195bucks for 600ft of it, how does it handle? high or low stretch? this rope will be used primarily for natural crotch rigging so im hoping to get some feedback on it, thanks
 
3 strand is super high stretch when compared to pretty much everything else on the market. It will be very abrasion resistant and would do well in natural crotch rigging.

Have you considered an affordable 12 or 16 strand? Maybe arborplex. Super cheap, with less stretch than 3 strand, and rugged, too.

Are you thinking 1/2" or a bigger line? What are the loads you are dealing with typically?

love

I have thought and used 16 strand and it glazes too fast for my liking. I have thought about arborplex but it seems a bit expensive when compairing it to the 3 strand and I'm looking for something with excellent abrassion resistance.

Stupid question but how well does a grcs handle the 3 strand? With all of that stretch it sounds like a lot of pretensioning maybe in order
 
Stretch schmetch. Had a 120' length of Promaster for about a year until a groundie flipped it into my saw as I was cutting. Never used it in the GRCS, but don't see why it wouldn't work just fine. Treemaster... now that's abrasion resistant!

now thats what I was hoping to hear. I'm interested to see how well it holds up on these big trees we just landed as removals.

3 strand is inexpensive, but may be not worth it in the long run. Like Nick asked, what kind of loads are you dealing with. Are you going to be rigging near obstacles where using a stretchy rope might not be appropriate? If you're riggin large wood, a 1/2" rope has a SWL of about 1,000 pounds.

We use 1/2" 3 strand ropes for lite rigging (500 lbs. max). It's a handy rope to have for trees in the Chicagoland area. I would say, it's the lowering line that gets used the most. Most of the tree removals we do are in confined area's with limited landing zones. A 3 strand is perfect. Once we get to big wood, the DB's (Sta-set, stable braid, double esterlon) come out.
For any lifting, we use a 'low stretch' DB (Endura braid, Amsteel II, Pro-Force) to help prevent "shock".
The GRCS works the best with DB's. I've only used 1/2" 3 strand in it. It winches the rope fine, but there is alot of strrreeettcchh.
 
If you do a lot of GRCSing, I wouldn't get the 3 strand because you'll be wasting a lot of time taking the stretch out of the line before you actually start moving things.

Maybe you need 2 rigging lines? 1 for natural crotch, and one for GRCS/pulley work?

we are now switching our focus to a 12 strand. Possibly the buzzz line, has anyone ever used this line? If it were up to me I would have a lot of true blue on my hands but my boss is worried that, because trueblue doesnt have a core the rope will be difficult to untie when rigged with a heavy load. I know they have a 12 strand with a core out there some where. Any ideas? Any arguements I can give my boss to buy some trueblue? Thanks for your support thus far guys.
 
We use true blue for all our rigging. As long as using bowline or cow hitch, never had a problem when untying. We used fig eight knot on a carabiner for knotless rigging. Good luck getting that undone. Hope that helps. Its very good for rigging, but i haven't used much else. Ohh i find that it flattens some under a lot of weight.
 
thanks derrick, ill make sure to have this qued up on my iphone when i go to work on monday for my boss to read

norm, i havent had a hard time untieing the knots, ive never really used trueblue, but my boss complained about it being difficult to untie because of the lack of a core, he doesnt know.... anything. he is a glorified salesman and isnt up to date on modern arborculture, heck, this time last year i was still spikeing all of my trees. but it can be rather difficult to break him in on newer tech stuff, he still prefers we glaze up a hi-vee line because its tried and true in his eyes

ah the struggles between owners and climbers continues
 
I've never noticed a difference in untie-ability in ropes with/without a core. I don't think there is a difference.

Buzzzline is good. Very bright- makes it easy to see in the tree.

Also might want to have him think about the cost saving of using a pulley. It'll cost you upfront, but ropes seem to last forever when you're using them.

Hey nick, we use pulleys but when I'm doing removals or light rigging I prefer not to chase a pulley or block after climbing around. If we are doing extensive rigging and I know that I'll be in the tree more than an hour or two I'll climb and set a block for good measure. Im going to steer him towards the true blue. I like how supple it is and its low stretch and natural crotch rigging abilities. Can any of you think of a better line for the same price or cheaper
 
My experiences with True Blue for rigging have been positive. In comparison to an old 16 strand climbing line (Arbormaster) the TB has doubled its rigging life and yet to glaze but twice (somehow got a small glaze on there once in the past year). The 16 strand lines glaze up because (I think) they are more tightly woven and generally stiffer... but that's why they are for climbing and not rigging.

As for knot untying ease, I'd say that the stiffer the rope it seems to be easyier to break the loaded knot, but as a wise man once said (up above this here post) you are probably overloading your system if the knots won't untie.

The real joy with using TB is on the ground: it's very supple and feels way better in the hand than double braids etc. Smmoooth stuff. As for stretch however, I don't feel it fits the bill of a low stretch line... climb on it once and you'll feel the bounce of your life as far as arborist ropes go. Though that's not a bad thing: load up a tip tie or speedline and you can slingshot a small limb over a remaining limb or away from the climber etc. into the clear for safe lowering.

climb on
