i tested my 175% overdrive this morning, and found it to be too much to control, so i ended up switching back to 150%. i also kept the tighter spacing and superglued a short nub onto the front center pinion (like the nub on gen1 cones) to keep it seated in on the "D" shaft. the mesh has improved significantly and is much more consistent than in its early stages: i can actually turn the front wheels and the gear mesh is strong enough to turn the rear wheels with it.
