Thanks Adam good stuff, a couple extra things.
1 - On CoinMarketCap there is an asterisk (*) in the Circulating Supply column that denotes whether a coin is 'mineable' or not. This keeps you from having to click on every coin.
2 - Once I've found a mineable coin and have clicked on its name, I like to go to the 'Markets' tab first to see what exchanges they are on since I will eventually have to deal with those exchanges. ( take into account how old the coin is, if it's new you might just have to hold the coins until they get on exchanges you like )
3 - In addition to #2, the exchanges they are on can be important. I stopped mining Verge to mine RevolverCoin because my setup was mining them pretty quickly. However, revolver is only on Cryptopia and the act of exchanging it to Litecoin (or some other popular coin) and then trying to move it off Cryptopia cost me ridiculous fees. This isn't necessarily a deal breaker but I chose to go back to Verge for the time being.
