If I recall properly, the Precision OS had a straight 20mm beam and was a pretty stiff, relatively low-power, stock. Other Prince freaks - please correct me if I'm way off here.
So, if I'm not completely wrong, dare I suggest the Hybrid Tour, even though it doesn't come in an OS?
If you are interested in seeing how the new Prince line feels, maybe try the Hybrid Tour or even the plain Tour that comes in a 107?
