NV,
For what it's worth. I've shot the Spitfire a lot. They produce a heck of a wound, with very short blood trails.
I had to be careful with them though, because my quiver would slightly open them sometimes. I got used to closing all of the blades every time I took them out. I've heard stories of some that hit the riser upon release.
The last couple of years I've tried the NAP Shockwave and now the Scorpion. I really like the Scorpions' cut on impact tip, and the blades will not open prematurely. It also has a smaller diameter, and I like that for bigger game. They both fly like the Spitfire, and field points.
