Y-straps are good to go for normandy, on any non-M36/40 tunic. Those tunics mostly had internal suspenders, and thus the troops were not issued y-straps
My y-strap bitching from before 2.0 was because DAK tunic didn't have internal suspenders, so they needed the y-straps
As for american skins, I honestly just want to see a nice infantry division skin.
