Been looking online to replace my K66 cushions . I came across an eBay listing showing a 100% gum black rubber cushions.
https://www.ebay.com/itm/K66-Pool-Table-Cushion-Set-of-6-BLACK-/253259369914?_trksid=p2385738.m4383.l4275.c10
K67 Billiard cushion used on high end tables that require K66 profile rubber. This is the same profile as K66 cushion except that it does not have the "groove" in the back side.So does not having the groove affect the rebound action of the cushion. I can see the adhesion effect of no groove being better. anyone have any experience with these cushions
