Why am I not playing at Cryptologic?

[aflaba2]

I play 5/10 at party. I don't know what I make in the long term, but for the sake of discussion let's say I make 1.5 BB per hundred hands playing 4 tables.

That's about 300 hands.
So my hourly rate is in the neighburhood of $45.
That's not bad.

I just surfed bonuswhores and checked out the bonuses, just for recreation. To my surprise the bonuses seem to be great!

At Bayou Poker they have unlimited bonuses that according to bonuswhores clear at a rate of $38 per hour when playing tables of 5/10.

At the Cryptologic network they have loads of bonuses every month that even though the bonuses have becomed harder still clear at a rate of $60 per hour.

So why am I not playing at Bayou or Cryptologic?

On both networks I can get practically unlimited bonuses that clear at

Bayou: $38
Cryptologic: $60

compared to my current win rate: $45

At Cryptologic I can even be a modest loser in the game and still improve my win rate!

So what do you say?

Am I missing something or are the bonuses as good as they seem?
