Hey there fishon01.I haven't been involved in bowhunting near as long as some of the people on the board,but I have tried to be a good student,in order to become better at it.What I have read and been told by some reaaly good bowhunters(and great archers)is that 7" is a good medium when talking brace height.As brace height increases,a bow GENERALLY,is more forgiving of minor flaws in our form.When it decreases from this point,it USUALLY is a little less forgiving.There are trade-offs of course.As was mentioned earlier,lower braced bows are usually speed machines that can really smoke an arrow.For an archer that has flawless form(definitely not me!),this is great.Personally,I'd rather have a little less speed,and a little more forgivness in my bow of choice,and then try to make my bow shoot as quietly as possible.
