RE: Enough KE for Spitfires?
In a three blade head the Steelheads are an excellent choice. I also like the Rocky Snypers, I know they are only a two blade, but the cut on contact tip really opens up the wound channel. If you want to stick to a new archery product head the shockwaves and the new scorpion should be great. I have not tested the Scorpion, but it appears to be a shockwave with a cut on contact tip, so it should work great. The shockwaves open faster and penetrate better than the spitfires.
