RE: brace height
eyenutz, welcome to the board.
It really depends on personal preferences, and the type of shooter that you are. For me, I wouldn't buy a bow with a brace height of less than about 7.5 inches of brace height. But that is only one part of the total package. I prefer the brace height, because I want a forgiving bow. If my form is slightly off, a bow with a larger brace height should be more forgiving to me.
But there are expert archers who really don't need that much brace height and still shoot fine.
