And the HR is slightly faster than regular 860, right? Given I play a mix of games, but spend a lot of time playing straight pool, if I were to get some Simonis over, HR might be the best bet of the three main Simonis cloths.Agreed. The difference is negligible at best. I play with a variety of sets: Centennials, Dynaspheres, Cyclop, Aramith Tournaments, Cosmos, etc. I think the key factor is the cloth. HR is supposed to be more resistant to wear.
