I'm currently looking for a pool to mine on (currently I'm using the EU-pool from eligius). My hash rate is ~300M.

So I was wondering if it makes any difference, whether I mine on a large pool (discovery of new blocks every 2-5 hours) or if I mine on a small pool.

From what I understand: if mining on a large pool, I will receive (or at least promised to receive) BTC more frequently.

Are there any other differences/advantages/disadvantages of mining on a small or large pool?
