In ring games you will have to make better postflop decision, compared to SNGs IMO. But your game probably needs that. Maybe you should try starting with full ring instead of 6max and then make the move to 6max.

go thru these stickies. Don`t try to incorporate everything at once into your game. Do you have Pokertracker / pahud ? If not you should consider getting it. Since it will help you alot, and you could post some stats.
