I was shooting 450. 2 years ago I switched to deer crossing archery. 340 grains total. 26 inch draw and 65 pounds on my destoryer. I've shot 6 deer with this set up, furthest shot being 43 yards. Blew through all of them. Ya I dropped 120 total grains but I gained a crap load of speed. I shoot a one pin flat to 28 yards. Untill I see negative effects from my faster,lighter arrow I'm sticking with it.
