some folks in the know are telling me those bows like their spine a little weak.. but anyway, on to this speed thing....
why? are you hunting road runners?

there is some company out there, a guy who used to post here a lot shot their bows, and always under 5 grains per pound - and i think they warranty under 5 grains per pound. i'm thinking high country, but i could be wrong. you may want to figure that out though.
