I play a lot of live limit cash and personally I think its incredibly boring. No limit is almost certainly more profitable, every hand is an opportunity to play for stacks. Also the games play so much differently.
People overplay hands like AJ AT KQ KJ in limit games and float multiple streets with one pair hands.
Then they set mine but don't realize the implied odds
don't exist because its LIMIT.
I think I would rather have Ah3h at a loose passive full ring limit game with a bunch of fish than aces.
I still play from time to time though, so it can be fun.
