I want to (finally) get started on my Cybertron Metalhawk custom, but something's standing in my way: LoC Starscream's pins. I know how to remove pins, but I'm having just a bit of trouble figuring out which end of the pins in his arms is the checkered end. I'm suspecting it's the outside of his arm (under the wing) but can't quite tell. Lobo's tutorial mentions that the plastic around the checkered end should look rougher, but the surface isn't flat like the Alt Smokescreen in his pictures. Also, has anyone managed to remove Starscream's head?
