Send me your tired, your ugly hitch cords...

its a VT tied with a loop rather than an eye to eye. I cant figure it out how to succesfully tie one. I think it performs like a VT
 
Ha! This thread has over 1400 views and only 8 cords sent in.
That in and of itself shows me something. (lots of folks are eager to contribute their opinions but few are willing to stop by the PO on the way home)
Since there were only 8 it would be really cool to see the pics of all 8 after breakage. I think I might be able to pick out mine from the 3 beelines.

Thanks again for the time taken from your schedule to do the testing Tobe.
 
and again...

Thank you Tobe. I cut my split-tails when I retire'em so I didn't have anything to send.

To me this test supports the idea that spliced hitches are plenty strong and if I read this right, the splices held and the cord failed in section. That's great news!

I've gone back to plain old Tenex, to me it's more responsive than any other material and it makes the VT 100% reliable without having to set it. I'm thinking 3800# on a single leg is way more than enough... which i like.
It wears fairly fast but Tenex is dirt cheap and simple to splice. I feel pretty confident that if I had to bail out of a tree at high speed the hitch may be ruined but it will get me to the ground safely.

I like Ocean and HRC and Beeline and I've sung their praises many times but lately, meager old Tenex is my #1 cord. After my bridge separated I've gotten leary of aramid cords with covers, if it's aramid, I want to be able to see it.

I read that same article Tobe and it explains some things, like a 7 month old 22kN dyneema runner that failed completely under moderate load... looked like it was cut. It also fits into the broken aramid bridge thing. Dirt gets into the fibers and because of the extremely focused bending stress, more fibers are cut faster. That's nothing but dime story theory but it makes sense.
 
Interesting that the beeline looks to all have breaks in the core but not the shell and then separated at the splice. Would a grizzly splice yield different results?
 
i broke a beeline and it broke right at the end of the splice. that particular splice did not have a taper. I have since been putting as nice taper in my splices. I have seen proffesionally spliced beeline and HRC with out tapers, thats why I tried it without a taper. I broke it while it was being used in a sled hauling rig out of a backyard. It was eye to eye and a truck was involved but it was the weakest link

I would be curious to see the breaking difference without the taper or with a taper.
 
Tobe:
THANK YOU for your commitment to safety in general and for doing these tests. very valuable info. I think bing mentioned some tests where beeline broke right at the end of a non-tapered splice. Kind of looks like that is what the grizzly spliced pieces did, unless I'm missing something.
