You may be best on a PPS+ pool something like viabtc.com
Or you could take your chance with one of the local Bitcointalk pools such as Kano.is they have not hit a block in some time but user count on the pool is small so if they were to hit a block and you have been mining there you may just earn more than you would on PPS pool but again it's timing you may need to hash for sometime before the pool hit's another block.
My choice would be either Kano.is (possible long term mine for better reward)
Or
ViaBTC for daily gains of BTC
Hope this helps.
I suggest six units on viabtc and one unit on kano pool
