I tried short handed for quite a while. You get through alot more hands etc which is a good thing(if you can win on them). But there are other things which counter balance this. When you make hands you are less likely to be paid off as less people are likely to be in the pot. People are more likely to notice how you play when only 6 are on. At a full ring game with people coming in and out you can be the tightest bastard around and then bet when you have a hand and people will still pay you off. At short handed games you have to play more hands and play your opponents more. You have to make plays and win pots when you don't have premium cards. This can of course be a bit precarious. Very lucrative if you are good at it but dangerous none the less.
At full ring you can sit tight and then bet aggressively when you get something and you've a good chance of being paid.
You can't hang around as much short handed cos the blinds come round so quickly and you have to be constantly making plays for them.
In a sense you can almost sorta switch off and play on auto pilot at full ring games. Yeah you should be paying attention to how people are playing etc etc, this will help but you can get away with not paying too much attention, You'll miss a couple of bluffs etc you might have caught otherwise but you can still make money as long as you are sensible. When playing alot of tables you will tend not to pay as much attention as perhaps you "should" anyway.
