Potential Alts!

[Kakashi Hatake]

The only advice that I can give it to pick someone different enough from your main that it keeps things interesting. If (like me) you have two characters that are very similar in personality or play style, it can lead to stagnation. As much as I'm rooting for Konohamaru/Yamato, they miiight be too similar to Link to keep your attention (that's not a slight against you, I'm just speaking generally). I'd suggest someone silly like Killer B (if you can handle the raps =P) or a villain. Just my opinion.
