You should also try our NiceHash / WestHash stratum pool service. Take a look at pasts stats for SHA256 on our NiceHash (Europe): https://www.nicehash.com/index.jsp?p=stats and WestHash (USA West): https://www.westhash.com/index.jsp?p=stats ... as you can see you can expect >10+% better payouts then regular direct Bitcoin mining on PPS system and regular daily payouts, no dependence on luck.
I vouch for these guys... I use them plenty.
gotta love NiceHash/WestHash.
I am comparing s0br's pool to it today to see if there's much difference. After 2 hrs, (yup- a very short time period), I am liking them both.
