Yeah, I still think Production is the best game. I am sold on RDS for carry. So even if I went back to Production, I'd still shoot CO to stay in practice with a dot. But I'm having fun with CO, even though the 23+1 mag capacity requirement is annoying for multiple reasons.
I am seeing a lot of people getting good fast with CO. That wasn't the case with Production, which seems to require more work to be competitive--at least at up to A class. At M/GM, CO is highly competitive and I'm still struggling to get to where I want to be.
