UCO, I am 99.9% sure I' m right (in this case). And although I really like the Spitfires, I' ll agree with everything you say in your last post. You got to have an exit wound to get a good bloodtrail. And I' ll be the first to tell you .....if you do , their awesome. But I' m sure the Shockwave is about the same!!
JMHO....but if the Spitfire did open fully on impact ..........I think they would be the best broadhead out there for 60#+ KE bows!!But since they don' t I' ve got about 6 other designs I keep trying to find something that does it all.........and still haven' t !!

Good luck this season!!
