I've tried leg straps with a sugoi and a zubat. Guys either love it or hate it. I hate it. I've tried all positions on both legs. Give it a try though, you may love it. I think the sugoi is probably a better leg saw than a zubat.
I use my zubat every day and love it. I often use it to finish topping cuts, or finish the back cut on delicate hinges. It's a lot safer than using the chainsaw. I also reach for it a lot on palms, and smaller limbs. I go through a blade about every 3-4 months. I carry my 200T on my right side, hung on a dale jury bungee lanyard hooked off the saw attachment point on a treemotion and then short hung on a large petzl carritool beener on the right side. Crap does get caught up around the saw and beener, like your pole strap, climb line etc. Not so much as you might think once you get used to it. It works well short hung, and I like it there.
I carry the zubat on the left side of the harness with the butt facing forward. I can reach across my body with my right hand and easily draw it. Of particular mention is that I don't hold the scabbard with my left hand when replacing the saw. I've gotten cut up a few times in past doing it. I now sheath the saw by just guiding it back into the scabbard with my right hand only. Those things are just too sharp when new and go right through gloves.
