Where to play?

I started playing at pokerroom.com due to someone telling me about it a couple years ago, just playing with play money. In the last couple of months I started playing with a bit of real money. After picking up HOH, since then I have also read HOH2. I started out winning went up by 50% of my roll, but since then have been in a slow slide downhill. I mainly play the 6s sng's at pokerroom.com, occasionally doing the MTTs but find myself waiting on hands and getting blinded away by the fast (to me) blind structure.

I have briefly tried pokerstars and party but did not like the interface in comparsion to pokerroom. Are the blind structures much different? From reading here it seems those 2 have the highest fish count around, but for some reason whenever I have tried playing at either I just don't like the look or how it plays. I kind of like having the option of only using a kb if I feel like it.

Anyway thanks in advance for any advice.
