The thing that worries me about using Kerry's protectors vs. Cliffy's, is it seems to me Kerry's only protect the vertical portion of a kickout hole--while Cliffy's protect both the vertical and horizontal portions.
Take a game like MB for example. They're all worn at the Mosh Pit--at the right angle of the kickout hole and beyond...exactly where a Cliffy would protect a game from wear.
Am I missing something?
