Recently, a few posters have posted pictures of the so-called Amplifeel handles with what are supposed to be basalt? strips on the handle. Sort of impressed because I'm not too crazy with companies and "new" technologies. They always sound like marketing bs to me. Anyway, I'm proposing an experiment that'll help tell us the effectiveness of Amplifeel, who's willing to do it? 1) Remove the Amplifeel basalt strips off of the PSBLX90, and play with it. 2) Somehow add those Amplifeel basalt strips to the handle of previous generations of the Tour 90's (Tour 90/N90/K90/BLX90).
