Looks like a sweet ride Doug.
There's one important aspect about your track design that you failed to
mention: the rigidity of the 90 degree angle between the chain and the
tread. If that angle is not held rigid over the life of the track, the
probability of throwing a track goes up. Attachment links significantly
increase the rigidity and therefore the reliability of the track.
Personally, I think that your attachment chain design is as good as a
chain-based design can get. End of evolution.
The performance of the TTS design is legendary and well-proven on the
battlefield (which makes all other R/C tests look like kindergarten
projects). Will's and Doug's attachment chain designs are also
seasoned. Not as good as TTS, but definitely battlefield approved.
Basically, the last category in track designs that hasn't been fully
explored is self-linked treads.
If you're going with 3D printing for prototypes and injection molding
for production, you might as well design an interlocking tread that can
be pinned together just like the real thing. When used with a properly
designed drive cog and guide tooth, you would never throw a track.
Moreover, a cleverly designed set of parts could be used to make a wide
array of different tracks. Single-tooth, double-tooth, offset tooth,
narrow, medium and wide tracks could all be built using the same
elemental parts. If you combine the pioneering work done by Garnet for
T011 with 3D printing and modern injection molding, I think the result
could be successfully battle-tested and used on a wide-variety of vehicles.
Loic and FoA have pushed that frontier further along with their scale
metal track links, but I don't think the evolution is done and a
semi-scale version in plastic would be greatly appreciated in many
different R/C worlds.

Here’s the new tank I’ll test them on. The hull is mechanically
finished. I just need to wire it, add tracks, and try everything out.
