Speedo: InchUp refers to the height of the wheel. An InchUp wheel is 1 or 2mm taller (I don't remember the actual size).
Concerning the MIP CVD... Do you know the part number? The Ti universals sound great. Are they available in the US?
I've used the Proline Gumby, and Velocity wheel. While I like the look, I had problems with them bending and becoming wobbly. That's probably not a problem with the Proline Dish type wheel. But I refuse to use the Stratus body and Dish type wheels.
