I have T-84s on my Pershing and also had T-80s on my Super`Pershing. Since Impact tracks are`made for Tamiys, all one has to do is Dremmel a second flat point on the sprocket hub for HL and they run great. Metal tracks , especially my T-84s, are`a bit stiff, but after a bit of running, they loosen up. I just wish I could get my T-84s to stay black, as rubber tracks don't have a silvery look. [] The winterketten I had on my Pz III never` gave any problem, other than maneuvering on grass.
