Andy, I haven't used the 3 blade so I cannot comment on personal experience however after using the 2 blade Snyper since 2001 I am amazed ever season I down an animal with them at the devistation. My friend Kurt (Q2INWHITETAILS) tried the 3 blade version and we were not as impressed. It's something about how they open wider at impact and then fold back. The 3 blade design isn't the same.

I've heard the same about the Rages, if you go with them, definately the 2 blade.
