I have this on my Nittaku Flyatt Carbon Pro blade as my FH rubber. My test was compared with a Tenergy80 FH rubber. The speed is fantastic with great spin. The trajectory is almost the same as T80. I do feel like the P-1 is faster during FH drives. FH loops with the P-1 are easier and more controlled for me over the T80. I love both the P-1 and T80, price on P-1 is much better though.
