I ran Nitto NT-01 for several years. before switching to Hoosier. Great track tire! Not the fastest one out there, but they are fast, withstand heat and wear very well. The NT-01 is the same compound as the Toyo RA1. There is absolutely no reason to heat cycle NT-01s. Just take it easy the first few laps. One set will last 6-8 track weekends. The only problem as an only tire is the tread is only halfway through the usable rubber on the tire so if it rains you are in trouble. And if you hit a nail or piece of glass, then there is no tread depth to protect from punctures.
Rain shouldn't be an issue for me. If it does rain, I could just use my daily summer wheels, which have Yokohama S-Drive tires.
