Ok, after spending some time cleaning up the DMF, it turns out that I was partially wrong on the twist test.

The flywheel rotates less than 15mm in either direction, 13mm to be exact, before it meets much greater springy resistance. However, once let go, it doesn't return to that middle neutral position. How big of a deal is this?

Sure don't want to spend another $750 on a new flywheel unless it's really needed.

If you have high miles and have been very aggressive on starts, I would recommend changing the flywheel. Usually a flywheel will have high and low spots and when you install a new disk and pressure plate you may end up with a chatter effect on starts. link for lower pricing.

How soon do you want to be taking out the transmission again? 10K miles, 20K miles?
You want the flywheel to last at least as long as the clutch, so if in doubt swap it out.
