Shinko's are not meant for racing, not even their "race tire" they are not speed rated properly and they are garbage anyways. SportBike Tire Service (STT Tire Division) has a bunch of deals on Michelin's. Plus as stated before 2CT's can be had at a good price now. As far as Power One's, they are the replacement for the Power Race. There are two versions, the commercial and true competition model. Commercial versions is what can be purchased from stores & dealerships. Competition models can only be purchased from race distributors. The Commercial model is a great tire and can be ran without tire warmers. Honestly if you could get a set of 2CT's I would pick those up as those will last you a lot longer then the race tires, and at your pace you don't need to be on a race compound anyways.
