When you install Artimus K66 cushions on a Brunswick or Diamond table, if you line it up flush with the top of the sub-rail like its suppose to be mounted, the point of the cushions are at 1 9/16" of an inch high...oops, to high. So then when you slide down the cushions to get the nose height at 1 7/16" which is the correct height, you have an 1/8" inch of sub-rail sticking out on the top of the sub-rail. Then when you remove that 1/8th inch to make it look like it fits right, what you've done is make it almost impossible for someone to come back and install the correct K55 cushions on the same table...because an 1/8th inch of the sub-rail behind the K55 cushions is now missing, and the K55 cushions are now sticking up in the air an 1/8th inch above the modified sub-rail, so that now has to be dadoed out, replaced, and re-profiled to accept the correct K55 cushions. And because the K66 cushions are designed to be mounted on a sub-rail with an 18 degree bevel face instead of the 21 degrees used by Brunswick and Diamond determined by the correct installation of K55 profile cushions, by sliding down the K66 cushions to get them to the correct cushion height, you've done nothing to correct the angle of the cushion to the balls, its still standing at a more upward angle than what the cushions were designed for, which causes the table to play sort of slow, because now instead of rebounding the balls like the cushions are suppose to do, the point of the cushion kind of lifts upward causing a pinching effect on the balls, which is what causes them to play slower than the correct use of the K55 cushions, designed for these tables.
Respond to that!

PS. Just because someones done something a certain way for a long time, that still don't make it right.
