Will try the DS Tracks from the DML StuG IV Early with Zimmerit. Last experience with DS Tracks wasn't so good - the DS Elefant Tracks broke and I ended up using individual link tracks.
As some other commentators have noted, this kit is something of a dog. It is missing the periscopes and other details, the loader's hatch doesn't open, the barrel does not stay in place, i.e., it flops down. I didn't even bother with the Thoma schurzen brackets because the attachment points seemed so weak that they would be guaranteed to fall off. Obviously, the somewhat compensating factor was the Orange Box price. New smart kit available from Dragon now.
