tnichols, I agree with you, on most videos I' ve watched in the Prime Time series, if penetration is minimal, the head is almost always a spitfire. However, on PT7, the first deer shot by Rick White is taken with a spitfire, complete pass through at about 25 yards broadside. They don' t get into the different bow set ups the guys are using, so one can only assume Rick' s is adequate, the others suspect for spitfire use.
