Thanks, I actually meant to say the special. But it sounds like given a choice between the special and diamond, you'd choose the special? I'm thinking that's the route I'm going to go unless someone has a compelling reason to pay more money for the diamond.No difference in quality. Obviously the pull weight range is different but the Diamond will break shorter and cleaner than the Primary. I own all three of the bolt models and for most things I’ll pick the Special. Nothing wrong with the Primary either.
