You are the man! 
How many blocks solved each day by the way? Am curious to compare with pooled mining estimation.
Have you tried other Ethash coins? Music coin maybe?
I am mining 2 - 3 blocks a day, best was 7 blocks at one day, but got them with a luck of under 20 % each.
Other coins are not such profitable like ethereum at time.
Got a private multipool with Ethereum, Ethereum Classic, Expanse with autoswitching between coins.
I am only mining the "big 3" DaggerHashimoto coins, but in fact only ethereum, based on profitablity.
Almost same as pooled mining, with 31.5 GH/s seems you get 2.4 ETH (Calculator say) ATM. But with solo mining, you have a chance to get 3 and more ETH. It seems a good choice for solo mining at yours Hashrate.
also quick question for you were do you get your info to help decide which coins you might try mining 
?
?Everywhere.
Old thread coin Ann, even Whattomine, Coinwarz, wherever. If you know the key, it will make you have a different view with regular miners when seeing some coin with technical info.
