My current setup is a Legacy set at 60 #'s and a 30in. draw. I shoot GT 5575 arrows. Ive been shooting 100gr mechanicals for the last 2 seasons. Ive been thinking, and I want to go back to fixed blade heads. (probably muzzies) I use a whisker biscuit and this is a part of the reason I want to change. When I push the mech. through the rubber band pops off and I have to put it back in place. Anyway, my question is can I get away with shooting 125gr muzzies with this setup? Will this increase my Kenetic energy? and lastly, should I increase my draw weight to 65#'s to get even more energy? (Ive been considering this anway) I know this is alot of questions but Im starting to get everything together for the season and I want to get some 125gr. field points if I do go this route. Thanks!
