I am just not a big fan of Cliffy's for saucers unless you are trying to cover a very worn area. I think they are fine for scoops but just tend to draw too much attention on saucers. I think your game does not need them for home use. I have had a WCS for about 6 years with practically no saucer wear (about like yours) and have not seen any change. I actually bought 3 Mantis saucer protectors like he sells for TOTAN but have never installed them.
