4/3 - Max Tables

Obviously playing 6-max on a site where they are all fish anyway is more monies than playing FR just because you get more hands in.

Has anyone tried the 3/4/5-max tables on the on-game network?
If so what adjustments would need to be made in order to ensure a good win rate from say 6-max?

Oh and random side question, does FR have less variance than 6-max?

Clar

in 5max you dont need to be so uber tight UTG, KTs becomes a fairly strong hand, small pps become less valuable but mid PPs increase in value.
