Here's a composite pic of a finished FoA FT-17 with "slender" 28mm Rif War figures.

I think it looks nice with those figures (I have added a base since I took the photos, have to take some new ones), and I think it'll work with chunkier figures (Artizan, Copplestone) if the latter are mounted on "thin" bases, or the tank on a base of similar thickness, which I would suggest since the mounting points of the tracks are comparatively small. It is a stable joint, but with the tracks and the trenching tail I didn't want to run risks and added a wooden base to mine.
