Hoping for some answers on 12-strand splices (sliding-splices, brummels/tucks, double-heads etc, any help is very useful!!)

[eyehearttrees]

1stly, am curious in-general whether you can make splice-crossovers longer than usual and, if so, is it simply a matter of sayingg "instead of the normal 15" fid for this diameter, I'll base everything off an 18" fid"?

I'd made all my slings w/ 3/4 polydyne but found I kept using my 3-ringed, 5' x-sling merely for the convenience as I made all my p.dyne slings with long tails, I'd never have thought it'd keep me from using them as frequently but that's what's happened...... would like to hear from people who have long-tails that need timber/cow hitching, and have whooopies/loopies, to hear how you see this....the long-tailed versatility seemed it'd make them ideal yet as mentioned I just go for my simple-to-install sling despite preferring my Safebloc :/

SO....got this spool of loose 3/4 TEC here, want to start re-making some slings (also have a #3['XL'] ring from Elevation Canada coming, ordered 6d ago and supposed to get here Mon , SO I'm hoping to learn some things, any&every bit of advice on any parts would be incredibly appreciated!!

1 - Anyone have links to a good double-head tutorial? Samson, thankfully, has whoopie instructions but none for double-headed stuff :/ They also lack:

2 - Tutorials for 'triple-tucking'/brummels (are these the same thing? Seems they're both just passing the rope through itself..)

3 - VERY curious to know *anything* about the "Special" type of whoopie that Sherrill/Treestuff make for their larger ringed-whoopies, for instance here's two of their 3'--->5' adjustable whoopies:
1 - small/normal type https://www.treestuff.com/rope-logic-1-2-trex-whoopie-with-x-rigging-ring/
2 - "special-whoopie" style on their 3/4 product https://www.treestuff.com/rope-logic-double-head-beast-whoopie/

^that "special-whoopie" has (2) back-spliced protruding ends (like a loopie) instead of the usual 1 on a whoopie, it also sseems SO much more of the body is doubled-up (which, w/ hollow-braids, seems beneficial IE almost "making it a double-braid" at those points!
Would LOVE to know how-to, or even the name of, that different type of "special-whoopie" so I can make my own, even w/ 1/2" line I'd prefer to be redundant yknow! At first I'd thought "Maybe that's a requirement of double-headed slings" but no longer think that's the case... To further 'confuse' things (for me!), I also am having trouble understanding how the rope-moves/how this splicing is under x-ray: https://www.sherrilltree.com/x-rigging-xl-beast-whoopie-sling-tenex-3-4in-3ft-5ft I ask because, while it doesn't have the double-loose-ends like the "special whoopie" w/ the double-head, it still has its ring-splice's cross-over so lonng that it enters(and goes through?) the cross-over of the sliding-whoopie-splice, almost makes me wonder if there's 3 pieces of tenex in some spots there!!

Thank you so much for any advice, am wishing I got 2-3X the TEC I did, hadn't been smart enough to really measure-out what a good whoopie w/ a Safebloc and triple brummels/tucks would take in terms of feet-of-rope

Oh and w/ how loopies are stronger than whoopies......When looking at that "special whoopie"

Notch Double Head BEAST Whoopie

So you have a big job and you need some big rigging - well you're in luck! Unlike other two-headed beasts, the Rope Logic Double Head BEAST Whoopie is made from mythically-tough 3/4" Tenex-Te

www.treestuff.com

^it makes me think that, w/ it being fully doubled-over looping, that this type of whoopie is probably either equal-to or superior-to a loopie instead of slightly weaker like usual!

Again thanks for any advice on any part of this, had a blast doing my double-braid splicing & am eager to do my 1st hollow-braid tonight

I know I can be verbose/wordyAF so since I can't get closure I'm trying a new way one more time, bullet-point

- Can anyone *name* the type of sling that one uses as "foot-stirrups"/rope-foot-loops? From 12-strand hollows they look like a whoopie that's somehow got 2 solid/fixed eyes, here's a pic from Samson's catalog:


^just a keyword I could google would be greatly appreciated, 'endless'/'loop'/etc are getting me zilch and I realllly wanna try one of those ^ !!

- Is there a double-head tenex guide anywhere ie slings like the x-slings with 2 rings on one end/tail of the rope? Would be so cool if Samson went and put them up already (was surprised to find they had specifics for Ice Tail when I got into splicing my own eye&eyes, they actually had specifics for my TEC whoopie too which was nice was nervous about proper buries on that and didn't wanna over-compensate and have a sling whose shortest length was 4'!)
Funny thing is I don't really need a double head...but if I can figure-out how the splicing is done and think I can do it then I'm totally making one (Elevation Canada two-packs are $75 on ebay and they're 10% thicker than a Beast ring, have one it's nice would def buy a 2nd to pair it with if I knew how to double-head a sling!)

Thanks *anybody* who can give *any* info on these (besides "don't bother with the foot stirrups thing" as I'm dead set on trying it already know my 'worst-case' design but know it's not what Samson's depicting there) Have been looking for a while now and can't find anything on these (or on prussiks/hitch-cords strength IE a 10k line is used as a prussik loop, what can it hold? Or rather "what can it hold at 90deg?" since force is applied in-line with its host rope of course)
