Supa, fwiw, I'm at 50nl atm and I still rarely flat 3bets OOP. You put yourself in so many spots postflop where you don't know where you're at and it can really fuck with your winrate if you try to playmaster everyone.

I'm not saying don't ever do it, but you need to have a solid read, and a clear, concise plan that you're willing to execute postflop before you attempt to do it. Otherwise you're just torching the extra 5-10bb.
