thx for the input guys. I will check out some deals on ebay for some of these heads but if they use a rubber band or o ring, I'm prolly gonna shy away from them. Thats the main reason I use spitfires now.
Hawkeye, I am not sure what to think of those SST. I used a SST fixed 3 blade on 2 deer last year and the blood trail was non existent. The heads were razor sharp and great shots on both. I really couldnt explain it but I ended up grid searching for both of them. I hope you dont have the same problem. Just wanted to give you a heads up.
