[Black winter day]

There are sites with good rakeback deals and much much greater table selection.
I get 39% rb on Interpoker (but you have to play quite a bit to get that) + 1000$ monthly bonus + a lot of promos the do.
That's at least 50% rb dealt each month, a lot of times more.

I prefer to play with 50% rb, softer games and a lot of tables (relative to WSEX) going than 100% rb , tough games and no tables.
