The Impact tracks may not look as good in the photo as they do in person. I have a set and they are solid closed pin tracks and have good track pins that do not slip out during use. You can get them at Mitosal Models. Here is their web site. http://www.mitosal.com/Panzerlll.html

You can get the Mato Tracks at Matomart, http://www.matomart.com/ I am going to try them on my HL JagdPanzer IV L/70 (V) I am working on right now.
