id switch broadheads allso , magnus 2 blades or the more expensive stingers , if you must shoot a mechanical , vortex pro"s are an excelent design with 1 1/2 inches of cut , alot less demanding than the huge cut surface you are using ,

my avitar was a complete pass thru that stuck in the ground 6 inches , 1000 pound animal , at 25 yards , i shoot 60 lbs and 28 inches , was using g5 strikers , they come scarry sharp from the factory .
