Why not go for just a single color? whats your most favorite lightsaber color? Then go for that.
Mine has always been blue so I'm going for a Guardian Blue Bellicose with Obsidian goodies hopefully this week. Guardian Blue Ultra Edge Heavy Grade blade, black blade holder, chrome button, Obsidian with red av button, li-ions, and long groove pommel. If you like green then Consular Green Bellicose's have been getting way popular around here.
