The best for me so far seems to be to go with MiningPoolHub which has multiple algos to mine, and then use this (https://bitcointalk.org/index.php?topic=2623352.0) mining software to mine with.

On MiningPoolHub you can select to auto exchange to a coin of your choice. But most importantly, you can keep the coins you want and only auto-exchange the ones you don't to a more preferred coin.
