FYI: I recently moved from slush also and after letting things even out a bit i'm getting the same amount of btc + alt coins... just need to wait a few days for the higher payouts to balance out fewer blocks found.

I remember you and I think you were the one told me about this pool right? I do realize that at this hashrate it is more of a lottery to find a block so there will be bigger differences in earnings from day to day but it even out.
