Small Site vs Party

[BookOfIcculus]

I play at a Small site mainly 15-30 with an unreal amount of calling station. It is amazing what gets cold called for 3 bets. And a aggresive pre-flop stategy will get you killed against 4 calling station who will cap it just for grins. I am thinking of switching over to party and was wondering if I should just stick at the samller site. Has anyone played sites like this and party that can tell me the differences?
