You should make the difficulty 2048 since it has no affect on profit
Ironically that might help level the playing field Set it to diff 10k
I got 3 pools on rotate, fast coin with diff 16 has raised accepted shares by 100 just since I started typing this.
LTC is on diff 32 switched to 128 and in a few mins its done +13 shares.
Middlecoin is 512 diff of course and in 5 minutes, it raises accepted shares by 1 share. That's it, near to a complete failure
[set cgwatcher to restart miner if theres no accepted shares, which will also take it to another pool till some time later]
