http://coinchoose.com/ will show you whats currently profitable.
However, most coins are just made for a quick buck from the creators.
I'd pass over FTC..
LTC has been stable, and the way its built leads me to believe it will have a steady value increase over the years, considering the support for it stays there.
Megacoin may be a good alternative as well. It's not worth much currently, but on the chance they implement zerocoin, then it may be a good gamble.
Best of luck.
(I've got a bunch of free anoncoins, and I'm really hoping their value picks up- They have a good foundation, just minimal support currently.)
