i played 5/10 limit on party for quite a long time and i never had any problem with people being tight, the players there are horrible...if u are worried about this, i recently switched to 6 max limit on party and people there are even worse then full ring and are incredibly loose...it takes a bit to adapt to the short handed play but its probably ur best option

A friend of mine has been playing 2/4 fr at party for 2 months now. He's a beginner and is beating the game for a shade under 2bb/100 (14k hands) just playing tight. And from what i've seen at 6max, the players get worse at 5/10.
