I think the current spear model is fine. I'm not a big fan of the spash damage, but oh well. There's a reason for the spear's simplicity: If you want multiple colors with weapons / tools, you have to use textures. Textures mean more downloads. All the work and extra download time just aren't worth replacing something that already works just fine. Plus, the maker would probably end up overriding the normal spear's datablocks.
