+1 here .... the more distributed the hash rate is the better and stable is the coin. Centralized mining in one pool destabilizes (every) coin tremendously. I personally don't care about 0 % pool fee's. Pools are unfair to miners which big hashrates, so I would always advise against using a pool unless a miner can not mine a single block within 1 or 2 months by itself. And there is the risk that the pool closes down (voluntarily or involuntarily) and the RICs in the miners account waiting for payout are gone/frozen. Let me remind you of the last big pool which had almost all the RICs network concentrated in one place. When they went offline, not only was a lot of money gone (frozen in their accounts) but also the difficulty sky high and it took days to get it down to normal in order do any transaction on the network. If this happens again RICs is going to be kicked out from the last few exchanges.
