Roger, The Sequoia is a little too lightweight. Not real comfortable on a big removal. I'd get the Tree Austria III. It's a great work saddle, I use it more than any of my three saddles. I've relegated the Petzl for classes only and the rescue bag.
Mickey is on his third one.....
I'll have to peruse it more closely next time he works with us. I want to have a rope bridge....perhaps it is moddable. I'd like to have the option of a chest harness/suspenders on my next saddle---for the double duty of saw support, keeping the saddle nice and high, and for SRT....
I use my old Versatile for removals, and have Travis's old Traverse that I could set up as a replacement..it's also a medium...for 10 years now, I've fought that Versatile Small...everything is too close together, and I can barely fit my lardass into it...besides, the weak tool loops have long since broken off, which I replaced with string.
I'll have to try the Sequoia SRT, but I'd hope it will be an upgrade over the B'fly1 for pruning. Wish it had wider leg loops, or stiffies like the Kolibri
