What exactly are DS tracks?
Dragon Styrene,they are a Dragon invention,better then the old "rubber band"tracks,they can be glued with CA glue,they paint and weather well initially,they look decent especially for live tracks,or German armor where you might have skirts covering the top run,but I've found some of my older builds they are getting brittle and cracking.
They are sort of an amalgam of styrene and vinyl, so they are bendable but also can be glued and painted, which is the old hassle with vinyl tracks. They are one piece.
I don't much care for them as they are difficult to be made to sag convincingly.
It does depend on the subject. For an afv where large parts of the track are not visible, because of side skirts, or live tracked vehicles where they stay tight, they can work.
For vehicles with visible sag, in particular something like a T 54 where there's a long run of hanging track, better to use individual link.
I've had very good results with plastic individual links, Dragon Magic Track, AFV Club track.
I followed the doog method. Lay them out after assembly, brush on solvent on the inside face, wait 45 minutes, place and position on AFV and build in sag in the right places.
For the Tiran 5, I used Friul tracks. They cost a bit, however I found that mine had no clean up, no redrilling of holes, and their weight alone made the sag look right to me.
