Oh thanks, I wasn't sure if this was a new overgrip that came out or something because I've never heard of it until now. Will have to try this out.
Ya, I think RZR Tac is a new branding for them. I'm willing to bet that this new RZR Tac is actually the old Gamma Supreme, just rebranded. I can literally have someone wrap my racquet with an old Gamma Supreme, a new Gamma Supreme and a new RZR Tac and when I pick them up, I know that two feel the same and one is just a tad softer. The softer one (more spongy feeling) is always the new bullcrap Gamma Supreme they came out with.
