What\'s the world\'s fastest false crotch?

What is your fastest system for doing short, quick advances of the climbing line, or quickly adding that last 10 feet to your final TIP?

Here's a short vid showing the U-SAVER installed without a throwline and put up "backward".


You Tube


The only thing I've found approaching this speed are those nice Dan House Sleeves from Luke, but that's assuming I've got it pre-installed over my hitch. If I have to put it on for the toss, my big fat Arbormaster eye takes some hassel to worm through even the 3/4" sleeve. It works, but any suggestions to speed that up?

SRT base tie, or Secret Weapon style for a floating DRT tie in point.
 
Re: What\'s the world\'s fastest false crotch?

What about a short length of stiffening wire bent double and run through the eye, and then back through the sleeve so that you can pull the rope back through?

Tom, the more I see of the U-SAVER, the more impressed I become!
 
Re: What\'s the world\'s fastest false crotch?

You could also use a micro pulley on one side, and a carabiner on the other. The micro pulley would stay on the climbing line, while the carabiner could be removed, advanced, and reconnected as desired.

Yep a spliced eye pretty much defeats the usefulness of a conduit sleeve. If the splice is built very compact on an 11mm class arb rope you can drop a throwline end or accessory cord through the sleeve, tie to the eye and yank the spliced end back through a 3/4" inside diameter conduit sleeve. The easier thing to do assuming you have a spliced eye on only one end of your rope is simply install the sleeve from the other end and just leave it on the rope. For short sets advancing DdRT in a tree there's not much that beats a conduit sleeve.

For the short advances, a natural crotch may be quickest and least gear intensive. Part of the question is how much work will be done from the short advancement point.

Thanks for the comments, guys.

Hal, you have the best photo on the Board ... and the good humor to use it ... ;-)



I did two more vids showing fast crotching setups for M and V rigs:


V-rig

M-rig



What's good about this is that they're fast and you don't need any extra gear. What's not so good is that the 6-coil isn't your best climbing hitch. It's fine for excursions, for progress capture, and for work positioning. But if you're setting up to work an entire tree under a V-rig, you'll be happier if you grab an i2i and tie a VT or something.

Thanks again. Tom

I must be missing something here. Why would you use a FC if you are only advancing 5-10 feet and not at your final TIP?

On thin-barked species like beech for example you'll quickly dig into the cambium climbing DdRT on a 10 ft. set. On pitchy species like white pine (in the east) your hitch will seize up after a few pitches (no pun intended) with no cambium protection. All depends on your climbing style of course, if you're ladder climbing the branches with rope/lanyard as backup, not so much a problem.

Re: What\'s the world\'s fastest false crotch?

Nice job on the videos and configurations. This is only partly on topic but... the way you rigged the Pinto/prusik combo for progress capture on the M rig is awesome. For making SRT traverses I'm currently using a Microcender for the progress capture. Someone on the Buzz had already suggested using a hitch instead and seeing the way you set up the Pinto confirms it would be a smart approach with minimal gear.

Re: What\'s the world\'s fastest false crotch?

Thanks for the comments, guys.

You're right, Zach. I use this PDQ toss for some last extra feet for the ddrt TIP. But that's once per tree, and then only when you're not choking to the stem.

Much more repeatatatively, I use this toss for my lanyard. I use a DEDA climbing lanyard. Homemade: think two long CElanyards with their tails joined around my back. Very long reach when I want it. Setting a U-SAVER and climbing on the lanyard is my preferred choice over a re-direct for positioning cuz I don't actually have to get to the tie in to set and retrieve. It's a quick mini V-rig for work positioning. It works because the lanyard and the U-SAVER are quick to work.

But I do admit to being a about running rope over a natural crotch. I just don't do it. I know it makes me a less effective climber sometimes, but I just don't like doing it to the tree or my gear.
 
Re: What\'s the world\'s fastest false crotch?

Nice use of the Pinto, Tom. I think you might find some good use from a small grapnel hook (New Tribe) for setting a second TIP that is a good distance from the first TIP. See you at 'Grows'!
 
Re: What\'s the world\'s fastest false crotch?

Andrew, thanks for the comment. Yeah, the little pinto is awesome, espectially for the money.

If you try that configuration, be aware that the Tech Cord from All Gear is part of what makes it work. It's got a normal, rounded shape when stuffed with a buried tail for the prussik. But "unstuffed" it's got an almost flat, rectangular profile. It lays flat in the pinto and leaves space for a biner. If you choose some other 8mm cord, check out the space it will leave for you ... tenex doesn't work, for example.

Thanks, AJ. I don't know what you're SRT traverse looks like, but if you can get to the line end, here's domething else you could try:

Start with the prusik in the video but only do two turns/4 coils. Then take the pinto in one hand and the end of your line in the other. Rotate the pinto a half-turn to the left and feed the end through the braid you just formed. Then do a half-turn to the right and feed back back through from the other side. Go until you run out of cord. You do these half-turns back and forth so you keep the legs equal length and the pinto goes on straight. You'll wind up making something that looks a little like a VT. Not as good but it's got a better release than the 6-coil.

Definitely want the progress capture midline attachable/detachable. I know what you mean about the 6 coil being too grabby. Doing a traverse you want to be able to stop and start again especially on the uphill side. The traverse is set more or less horizontal but there's always a good incline to ascend on the far end. So... like secured footlocking, a prusik hitch is a problem if you stop, can be a struggle to unseat and get moving again. Anyway... the way you rigged the Pinto in the M gives me some ideas how to use a hitch for progress capture.

To give you an idea of what's involved in a tree-to-tree SRT traverse here's video showing a traverse last winter starting around 4:10 into the video

AJ, that snow climb looks like one hundred percent FUN. And the flyover was amazing! Did you schedule that? I heard one of them quack "I dunno. I didn't think they could climb either."
