RE: patriot single cam or pro38
I have a Pro38 Single Cam and a Patriot.
Get the 38 if it's mostly 3d. It's more accurate (IMHO) and faster than the Pat. Also - if you're shooting bowhunter class you can't have anything on the back of the riser so the 38 is a better fit.
I do like my Patriot but if I could afford it I would buy a new 38 & sell the Patriot - only because of the restrictions in NFAA classes and my reluctance to move to the open class.
Aim small miss small
