If you could pick one "alt coin"...

 FTC!

Right now, I would definitly say Feathercoin, is that because im heavily invested in it? Yes.. Is it a good coin? as good as the rest.

CNC and FTC

CNC

I'd go for LTC or PPC

At some point it's not diversification anymore. With everyone dropping their own alt coin right now it's impossible to say what is actually a viable alt currency and what is just a pump and dump scam.

Go with LTC. If you want to do more than 1 coin, then use LTC as main, and do FTC on the side.

Why pick 1 when you can spread your investment : )

I think cnc will do very well, its got fast confirm times
