I think it just depends on certain balls that come out. I throw a mixed arsenal of Storm, Roto Grip, Track, and Ebonite. My Rising Star, Nomad Dagger, 919C and Vital Energy just don't quit at all. However, my Anarchy has needed more attention since it does seem to lose its reaction quicker with the pearl cover. This means doing the surface prep and keeping it polished more often to keep it up. Same with my VG Nano where I have to resurface and deep clean it more often as well.
However, one of the balls that a lot of Storm people did not care for was the Invasion. That ball died very quickly for a lot of people. Less than a year later, Storm announced the VG Nano. I don't think that R3X Solid cover on the Invasion has been used again here in the states since.
