I just had to comment on something here. Please note that I too am a micro player and I make no pretense that I am some sort of expert so feel free to tell me to go jump in a lake.
However, Given that you are still in a learning stage of the game and still needing to ask questions about basic spots, why in the name of Chip Reese are you playing 8 tables of 6 max (or even full ring for that matter)? Playing multiple tables is one of the great things about I poker but that presumes that you have a solid fundamentally sound game to base everything on.
No offense whatsoever but do you really think that you have such a solid basic game? I understand that at stars you really need volume to get rewards but at 2NL and 5Nl especially your emphasis should be on really focusing on playing correctly in all spots and practicing fundamentals. In the long run you'll gain more IMO.
