Why don't yall 2TC?

I came across this video today and if you 2TC and rappel down this might be of interest to you. I am still in the early stages of trying to 2TC but I will probably give this a try since I do rappel down. Dual tether climbing with one rope - YouTube
I hope the weather gets better soon so I can get outside and play.

You must not have read through the whole thread then...;) that video's been shared at least 10 times! All good! And even though using 1 rope for both tethers is a good idea, I strongly recommend making sure its long enough to rappel on for any emergency. I like 2TCing out of a tree but always use a rappel rope as my main T just in case!
 
Interested in discussing the recent thread on the dangers of short static falls with regards to 2TC. While 2TC my max slack is somewhere around 18"-24", because I introduce some slack in order to move the top tether up more easily. I am currently using bluewater 11mm assault line (0% elongation).

If I'm understanding correctly a 24" fall on a fully static line could mess you up pretty good. It also seems that even a small amount of elongation might help a lot.

Does anyone climb with dynamic line? Looking at the specs it seems pretty ideal - 5-8% static elongation and 30% dynamic. So it wouldn't stretch too much just hanging there, but under shock load would have a good amount of give.

If anyone has used it for 2TC, does it make it harder or more annoying to have some stretch? I imagine a little bit of progress will be lost when you sit back down because of the stretch. But it might be worth it if it makes a fall safer.

Curious to hear people's thoughts and experiences. I've never fallen 2TC and don't plan to, but I'm not dumb enough to assume I never will.

Here's a couple 24" falls on a static line....now in the video I'm testing a specific hitch but the fall really wasn't hard on my body. Granted it was a "swing out" fall but all the same it didn't hurt me or anything.
And all that to say, I'd never, and most other 2TC folks as well I believe, would never have that kind of slack in a 2TC!
When you move up your foot tether to just below your main tether and weight it, you were in a sitting position more or less, thus when you raise your top tether, no matter how high you raise it, if it slips and catches the worst fall you'll have is back to a seated position....unless you're doing something really crazy.

That is super cool, thank you! That makes me feel a lot better. Correcting my post - the elongation rating of canyon c-iv and 11mm assault line are very similar so I would expect my ropes to behave similarly to yours.

With regards to the 24" of slack: when I stand up on my foot tether, it generates about 12 inches of slack. Then, I move my friction hitch down the tether 6-12" in order to give me more slack to work with when raising the tether, for a total worst case of 24". It's only for a second before I move the tether up, but the possibility is there. I believe this is how @gcr0003 climbs as well. I don't think it would be possible to climb large diameter, rough barked trees without doing this as you would be very limited in how far you can move the tether per move. When I'm climbing trees that I can wrap my arms around, I don't have to do this. But once it starts exceeding that, I found it to be super inefficient if I don't add some extra slack for the move. Very open to being told there's a better way. Perhaps your tether stiffener would help solve this but I haven't tried it yet.

Yes I see your point. I guess I don't do much 2TC on very large trees so I understand your need for constant adjustments on them...
The tether stiffener will make a huge difference in moving it up as it doesn't catch or snag.
I will say that I feel for me personally, and @NorthFourty 's video shows that there is a magic spot on your tether where you have just enough to release the tension around /he tree and move it up 12" or so without adjusting the bridge hitch. It does, I've found, require a very short bridge during the climb.

During our saddle testing, we did run a test with a Dynamic line. 220lbs dummy, falling roughly 4ft. The loss in force was noticable, but still in a window of force that can cause damage. With static line, the force was at roughly 890lbs (1800lbs is the ATM passing criteria). With Dynamic, it was at 780 lbs. Not sure if the rope size matters, but hte static was 8mm OPLUX and the Dynamic was an 11mm rope. Both with Shwabisch Hitches.

BTW, the difference between a 4 wrap Shwabisch and 5 wrap shwabisch was huge. 4 wraps slipped to the stopper (reduced the end force to 740lbs thought). 5 wrap didnt budge. I only mention that because some force can be reduced by knot selection and set up...not that I would suggest anyone count on their stopper knot!

If you were to tie a loop on the end instead of just a stopper and tie that loop back in either at your bridge connection or at your linesman loop would that allow you to run fewer wraps and eliminate the risk of coming off the end of the rope? That’s the way I typically run mine.

That's because you're 2Sloe and you're a genius!

Hey guys, I think we should have a 2TC meet-up!

Saddlehunter.com can pay our travel costs and maybe kick in for beer but we have to come up with the rest.
Since @tailgunner is the only 2TCer on the West coast (that I can think of) we can keep the gathering somewhat in the East to make it a little easier.

I think if we all got together and get to watch each other climb up and pass limbs, and transfer to platforms, and climb back down, and blah blah blah... we could really get some Sh!T figured out!

Each of us has got our own things that we do and we could share it or ditch it for what ol' So & So is doing...
If we could see it right in front of our face and then try it immediately afterwards on a tree right beside the dude then WOW. That'd be awesome!

I think we should have this party!!!

Shouldnt even be a topic.this vid is real.what people say on here about side loading is a wivestail.the vast majority will beleive in a myth if it makes them feel safe.thank you for not making me post this .big ups my dude.
 
Not one person on this forum is scared to use that 11 mill rope that broke.but people beleive that cinching and side loading are the same geometry,and that carabiner will break befor it bends,or befor the rope.

How 'bout spring gobbler season in Kentucky or Ohio???

Heck, we can have it at my place! (Western Pa)
I live on a 180 acre farm and my neighbor is 8,400 acres of Game Lands... (lots of turkeys around here)
