RE: Time to Vent.
Switch to a pendulumn sight and don't worry about the angle. (if you mostly tree stand hunt)
After each morning hunt I pick out a leaf of something on the ground at differant distances and take a shot at it. I'm always with 1" of my target using the pendulumn sight.- out to 30 yards that is. Never tried over that and wouldn't personally shoot past that anyway because the deer I'm after are to wired up and there's not telling which way there gonna jump when I shoot.
I hunt 14- 25 foot up, but usually at 22'.
