well a little late here, but I simply say, buy the bow that fits you best, all the makers these days make some great bows
speeds are all up there on high end bows, but tons get there by very low brace lengths
and to me the shorter they get the more form come into play, smaller upp's in form make bigger misses on short brace bows
and something else I come to find with the one's i played with
they like to slap your arm a lot more if your form is off, and or just wearing heavier cloths like when hunting in cold temps
just something to think about maybe
but I say your idea of shooting as many as you can is the best idea
see what feels like the bow for you! and not get caught up in name brand and speed hype!
