i purchased a reflex excursion bow from our local pro shop. my draw length was under 27 so we switched the cams from a hoyt zr200(i think it is zr anyway) to my bow. we also swapped the strings etc. is this the difference between the b-2 and e-5 cam? will my draw weight be affected? i reference the cams from the tunecharts on the reflex website. i know the relex bows are made by hoyt-are they the same cams?
