The best rubber I have tried, and I've tried them all. I play with the 2.0 version, and it's faster than Tenergy 64 2.1 and Spinnier than Tenergy 05 2.1. Bluefire JP01 has more spin, speed, and control than the Tenergy series. More and more Pros are switching from Tenergy over to the Bluefire series. The reason I was turned on by Bluefire JP01 was because Masato Shiono uses it and he raved about it in his review. The Tenergy Monopoly is over! Welcome Bluefire!!!
