I've recently been looking at the hash speeds of other pools, and now I'm a bit confused as to how one goes about actually choosing a pool. This is my current scenario:

Pool A: Less people, lower overall pool speeds. Blocks can take anywhere from 30min to 24hours (zomg..) to be solved, but on average it seems like it's 1 block every 5-7 hours. At my hash rate I get around 0.07btc per solved block.

Pool B: More people, massively higher pool speeds. Blocks are solved frequently, taking at most about 2hrs, but on average it seems to be less than an hour. At my hash rate I get only 0.007btc per block.

I get much higher rewards per block for mining in pool A, but it's disheartening to sometimes be stuck with a 12hour+ block. Blocks are solved a loooot faster in pool B, but over a 24 hour period or so, it seems I earn less in total than pool A.

Which one should I stick with?
