after these last 40k hands of 2nl, 5nl and 10nl all FR. my br has reached the $600 mark rolling me for my transfer to ftp...

should i be folding to 3bets pre less often? should i be 3betting more often?

should i be defending my bb more?

anything that really seem off or bad?

your suggestions would be great. recently my vpip/pfr has been more like 14/18.
