TFDarkside

Several quick questions, all responses appreciated! A) Is TM overkill for TD? any preferred for TD over TK for example? Is glossy armor in general bad for painting on? C) Is mixing and matching helmets and armor potentially bad? if so, rules? (I've seen some pics that looked like they were mismatched) D) Besides personal preference, is there a NEED for more black or white pauldron TDs over orange/captains? Thanks all!
