OK, so I was fiddling with my D-Day figures here, trying to get them all situated as I want them for display on a shelf here, and I'm about as annoyed as anyone else is with the one headsculpt as you can't fit a helmet on it...
We all know the guy I'm talking about.
Anyway, I found you can fit the Forces of Valor helmets on him pretty good actually. It's a nice swap really, to get him in a decent helmet. Dragon helmets also work well too if you've got them, but it's more likely you've got a FOV helmet handy. Very nice.
