BH,in the 5" to 5 1/2" range
Thats kind of low for a hunting bow , considering you will probably be wearing a winter coat while hunting . Something that may help is to use an arm gard to keep your jacket from contacting the string . I would sugest at least 6 1/2 inches of brace height for this issue alone . I can shoot a short brace bow farely well , but short axil bows dont work for me . I think the patriot dualy , or better yet the pro 40 dualy , or cougar mag nitrous bows would fit your "need for speed" well and probably shoot better than the black max you mention .
