generally i think it depends on the stakes. at the lower $1-$10 range i think that turbos are more profitable due to the type of players that like to play them. a lot of the time when playing turbos some of ure opponents at the table are playing multiple tables, usually playing TAG rather then LAG.
from about the $10-$16 sitngos i think its a genarally TAG but with more LAG mixed in.
once u get to the $20-up sitngos its almost all TAG play.
in general turbos are good from the $16 and below range i would say. with more donks goin out early and increasing ure odds
of cashing without doing much. above the $16 dollar range u can expect to be fighting for every chip.
