Niftech works extremely well on tracks that already have a good groove, but Niftech alone doesn't seem to work as well. Niftech doesn't settle into the carpet and create the kind of groove that Paragon, JTG or TQ does. Niftech is however, the ONLY compound other than Paragon I have found to give consistent bite for an entire 8 minute run. I guess in a perfect world Paragon would be legal everywhere and we wouldn't have to have this discussion.
