Removable helmets never really impressed me that much anyways. Unless it's a distinctive clone with a unique face or scar like the Clone Wars, where this doesn't seem to be an issue yet.
The only impressive advantage I see in these TVC clones is the ball jointed hips. No big deal unless they're riding something.
No thanks, I've passed on all these TVC clones so far. They are the big pegwarmers these days, along with the Sandtrooper. Whooda thunk?
From what I've read at GH the new AOTC clone is even more superior with jointed wrists and ball jointed hips. I hope he doesn't have this problem with a yellowing helmet. I haven't seen one in the wild yet though.
