HEY JEFF,
I know you know this, but please allow my retort:
With Flex Track, you can start with a fixed radius and go through an infinite change of radii until you merge into a Tangent track, with no intermediate steps!
You can advance from a "serviceable job" to a really smooth transition! Even where it isn't noticeable, why not do a perfect job while you're at it?
This is how track is laid in real railroads, using specialized plane geometry which includes Versed Sines and CoSecants.
BAD ORDER
