I'll add an unsolicited comment that the 'sharp' switches of the smallest radius, combined with the lack of a flange fillet on their wheels, caused me no end of grief for derailments to the point that I had to replace them with larger radius switches. Problem was consistently the radius transition between the points and the stock rail, diverging side, and no amount of filing and tweaking would fix it.
Not everybody wants a turnout that sharp, I was doing an actual Nn3 loop on a T-trak triple.... I like the stuff and it's almost as good as Kato, except for that switch issue. Right up there with the annoying factor of switchpoint derailments on Kato 4's, which is more fixable.
