Hi, i'm on maxbtc.com, right now. Been on mining.bitcoin.cz, btcguild, eclipseemc... What i realize in some big pools is that the hash power is so much i don't have time to hash... specially in score based pools, i get almost nothing.
Of course i'm in this for some money, but i like the idea of bitcoin, and like the idea that it's not centralized. That's what i don't think it happens in those huge pools. I would solo mine if i hadn't so low hash power. I know all about the pool comparison, but that doesn't answer the question or doubt that i have.
A constant or reliable payment for my shares, on a weekly or monthly basis, the most profitable of course. At the moment i aim at 1 BTC every 4 or 5 days. 4.1235 days to be exact, with 0% fee. I want to make the most BTC with my current equipment. I'm not into trading, i want the actual bitcoins and want to trade with them.
Ozcoin is a good choice for a primary pool. I would then use Deepbit and/or BTC Guild as a backup pool and then another small pool and solo miner as the next two backup's.
I have a similar has rate as you and get a BTC every 3 or 4 days, maybe 4 to 5 now with the higher difficulty. Sounds like your in line with your hash rate.
