The problem with mining new alt-coins is that as soon as you start, you can be sure everyone else is starting as well. The new coin pools rarely have a robust system set up to handle all of the traffic and you end up wasting days of mining time fighting with your machine and the pool itself. I've tried turning my miners toward many different alt-coins over the last 6 months and always end up wasting a couple of days doing it. Everyone pumps and dumps the new alt-coin and when you are ready to sell your pile, they are worth .0001 BTC a piece. WDC and FTC are a good example. In the end, I have chosen to keep my GPUs mining LTC for now.
