Those DMM swivels are nice for sure, quality piece of kit. I have them on my bridges. I like how the shackles are interchangeable to the different models, Nano and Focus.
I like that yellow wirecore...Petzl did you say?
That must have been really interesting Bob!
My tutor at College had shelves of bits of wood to illustrate almost every part of tree physiology and biomechanical stuff...it's catching and sparked an intense curiosity to know and see what goes on inside trees.
I love tree forensics! It takes me ages to split wood because I'm always looking at what had been going on inside before it got cut down.
I like to save clear examples for talks and demonstrations I do.
Relatively new to climbing, about a year as of March 2014. SRT now using Rope Wrench. Recently purchased Hitch Hiker, will try it out soon, as weather gets warmer. I'm not a pro arb, just in a learning stage now, pruning deadwood for friends and family, mostly with my Silky saw.
