Anyhow, The folding hood pieces. The hinge between each hood quarter on the original had two holes on one side that assisted you in placement of the rear of the forearms. Using said holes you could pull it apart making the rotation of the middle of the hood easier and then push them back together. No more. The outer most hole is gone and the piece is altogether shorter. It doesn't effect the TF whatsoever other than making it a bit smoother and less likely that you'll inadvertantly pull the hood apart.
I've not noticed any differences on SS yet but I've not spent too much time with him so we'll see.
