Thanks, it seems the rosso II is the choice of tire regardless. I didnt know if a 150 rear offered something better is all.

Your primary question is a bit of a silly hypothetical, which led the thread down this path.
My Don't even worry about a separate set of rims at all. You'll be a-ok on the ninjette at up to intermediate level track speed and beyond using Diablo Rosso II's. A single set will go many track days at C-level pace, and will last for thousands of miles on the street. No work necessary to change out the tires until they wear as usual, and no need to swap rims. Saves both money and time, with no real downsides.
