If you're looking for a pool, I'd recommend you look at the pool comparison page which you can find by searching and then find one with low fees, a good interface, and one that's reliable. Do not go with Ghash please as they are up to something no good, IMHO, or else are just really greedy and don't care about BTC.
IMO it is better to go with Slush's pool @ 2% fee. Now Discussfish is 2nd largest pool but you will have to mine in it at 4% fee.
Which pool would better :
1) Mining in a pool which finds blocks fastly @ 4% fee .
2) Mining in a pool which finds blocks in a time( neither faster nor slower ) @ 2% fee .
I excluded Ghash.io as it doesn't seem good.
Kindly,
