HolmenTree,
I've tried the SRT I use it once in a while, but most guys who climb SRT switch over to Ddrt once they are in the tree......or at least that's how I understand things. Ddrt provides for better position control once you're in and working the tree. Since the trees around here aren't too tall, I prefer to just climb Ddrt and work with it.
The hitch climber pulley is a great device. I use it in conjunction with a DMM swivel on the Tree Motion saddle. This setup provides for a second climbing line, or a long lanyard. I actually use my long lanyard far more. I've tried several hitches, but I really like the Distel, or the Schwabisch. Same thing....with the only difference being the direction of the wraps on the 4 over 1.
I really like the new climbing gear, and I want to personally thank Bob Underwood and Nick Bonner for helping me out. Climbing is so much more enjoyable now.
