RE: Stand heght for recurve?
I've never found a tree that I could get too high in. 25' is optimum for me, but I'd go higher if I could. Don't see a need to go a lot higher, but it depends on the situation. I've seen a lot of deer come in looking up, but they generally only look up so high. One thing to consider is the degree of difficulty is increased the higher you go--be sure to practice from the heights you hunt at. Regardless of whether you are 10' or 60' up a tree, 10 yds from the base of it is 10 yds--unless you use sights or gap, it can be tricky convincing your brain of that.
