For the most part DML has done Magic Tracks for just about every German tank available and probably then some. There is no reason for them not to include them when they have the molds and such. Lately I've seen some examples of DS tracks and to say the least they suck. The builders of these kits aren't happy due to the inability to get proper track sag along the top of the run.
Sorry but Cookie Sowell does not speak for every armor builder out there and not everybody wants rubber bands. Now granted I will admit they are better looking than previous rubberbands however people have told me that if you hit them with just a touch too much glue they will dissolve away.
I build mostly OOB and Magic Tracks fit what I want out of an armor kit. I'll say again, DML brought me back to armor with individual links and now they are chasing me away with DS Tracks. If I build a kit with add-ons and more detail then I will consider aftermarket tracks but I've preferred the Magic Tracks over aftermarket on many occasion.
Once again a kit maker thumbs their noses at the marketplace.
