Any ideas on how to choose weapons for a given power set???

My main guy is a Gadget hero. Because there are hardly any guildelines either in the game or on the official site, I decided that the bow looked neat enough.

I guess I was lucky and chose an appropriate enough Controller weapon, since it provides at least some Vitalization. But is this alright? Also, I suppose for leveling it makes less of a difference, if I'm not doing Alerts.
