Hi again,
I'm embarrassed to say that I still haven't made up some working friction hitches, even though I now have tow requests for sets of them. But I will. Really.
Meanwhile the matter of Samson printing instructions is ... tricky. As I said before, they still officially declare this stuff unspliceable, even though their own testing machine showed it to be a lot stronger than the knotted version. This might seem weird, but remember that, from Samson's perspective they just broke something some guy out there mailed in, and then pestered them into doing a test. That's why I've taken such pains to provide plenty of details, such that people who are already competent splicers can proceed with confidence. If you have some pull at Samson, maybe they could be convinced to make this an official splice...
Meanwhile there are two questions that need to be answered. One is, do you need the Dutch Hats. I suspect not, for most applications, and that they might only be worth the bother if you anticipate chafe and/or heavy UV on the uncovered core. The other is, will the tails I used make the rope too stiff to hold a friction hitch reliably. If it does, then we need to see more break tests, for the Brummeled-and-stub-buried option.
Fair leads,
Brion Toss
