I don't care what broadhead I use as long as it's a NAP Spitfire in either 100 or 170 grain all stainless. Been using NAP Spitfires and Scorpions (lots of success with deer kills) with Blazer vanes long enough to know they are not problematic expandable heads. My Desert Stryker will put them virtually in the same hole as a field point at 70 yards.
