Haha, nice call on the SPT's. I just got some new test results, it is by far the best value in the UHP category. Basically ranks at 90% or above of the best performers (PS2, PZero, KDW, RE050, etc), yet costs less than half of the price of some of them.
General Exclaim UHP's are also great tires. A little noisy and the sidewall leans a bit more towards the comfort side of the equation, but overall an excellent tire (regardless of price). I think the SPT is overall a better choice though (it does everything a little bit better).
