Painless you probably know as much if not a lot more about the PZ1/2/3 and 4 as I do,
The single most assuring thing about the Panzer 2 was the suspension was changed completely at least 3 times, none of the the Panzer light and medium tanks had decent suspension although the Panzer 4 prototype did give that tank a good chance with its torsion bar arrangement unfortunately the purseholders said no and the PZ4 was lumbered with the godawful 1/4 elliptic spring suspension that no one likes.
But with the multitude of choices on the PZ11 at least you have pretty much free rein in what you do.
I shall watch your build if you succumb with interest
