Anyone know why different colored overgrips of the same brand have different characteristics? From what I've used: Wilson Pro: White & Black White was tackier, and tack lasted longer than the black Volkl V-tac: White, Black, Yellow White & Yellow had same initial tack, yellow lasted a lot longer in keeping tack. Black - less initial tack, tack didn't last as long, and I would start putting little holes in the grip after 2 hours. None of that happened with white/yellow. Yonex Supergrap: Red, Black, Blue Black had most initial tack, then red, the blue the least. And blue's tack lasted the least. I don't sweat much in my hands FYI. And I use different colored grips purely for vanity reasons. Anyone else have these experiences with different colored overgrips of the same brand?
