This is a very specific question & I hope someone has some insight; I am looking for a recommendation for a single eye split tail for use with a Blake's hitch on Poison Ivy/BlueMoon? I was considering buying either 10mm EpiCORD or BeeLine but Sherrill Tree is recommending several 1/2" split tails. I thought this was odd since the climb line (11.7 mm) would smaller than the tail being recommended. Unfortunately, I do not have the luxury of testing multiple split tails before making my purchase as this is a large purchase of 15 sets for a new recreational climb set-up for a youth camp. Yes, I know, I know... closed system. I climb with a VT/ micro pulley 8 mil BeeLine eye to eye for my setup, but this is for community programs and we're keeping things simple. I have over 12 years experience facilitating groups on a traditional Blake's system, but it's always been on 1/2" 16-strand.
