I've tried to like the saddle thing, in theory it's good, safe, relatively light, go up most any tree, fairly comfortable etc. Maybe if I was younger I'd be all about it but now it's too many parts, too many steps, too much to do, too complicated...and in the dark? forget it.
I can walk up to a tree with my summit open shot and there are 3 steps, the climber, the base and the safety line and up I go. If there is a limb a folding saw takes care of it most times.
I might still try the saddle on some afternoon hunts when I've got more time and can see what I'm doing. It's defiantly the safest way to hunt from a tree and it can get you in a tree in places no other stand type would work, if I was 30 years younger I'd take the time to work out a system and use it full time but I don't have a time machine to make that happen.
