Well I just got back from a day at the bow shop and the range, the end result....(thanks to all who had informative posts and to all who awnsered my questions)...is I now have a dialed in rig (alli) spitting out 420 gr arrows at 297 fps and that ladies and gentelmen ends up at around 82+ ft/lbs. of kinetic mojo down wind! I am thinkin that a judo head would make a full pass thru on a deer at that energy. once again thanks to all who helped me and I can not wait till Oct. now baby!!!!!
