In this Manning video, near the end, the cushions are discussed. At 12:20 Heath points out that putting Artemis on a 7 or 8 foot table would produce ball travel "that would not be realistic":Drawing to the long rail one rail with too much angle. It is impossible to hold the cue ball like you can do on any normal table and you have to draw it 2 rails instead.
Also, when you end up with too much angle cutting a ball into the corner pocket down the long rail and want to go 2 rails to the other long rail. With this shot even if you make the object ball barely reach the pocket you still end up with the cue ball in the center of the table overrunning your position by a foot or more. The only solution for this shot is to hit the ball really firm and go 3 rails. This is another shot that should be possible on any normal table that just isn't possible on an 8 foot with artemis.
Basically with artemis on an 8 footer you will end up with a gaffy table that plays different than 99% of all other tables out there. I'm having a new 8.5' table made and I for this exact reason it won't have artemis. There was a pool hall here (that covid killed) which had like 10 Diamond 8 footers with artemis and the patterns you had to play on them were different than any other tables in town (including the two 9 foot Diamonds they had with artemis): all because of the rubber.
From what I understand situations like above are the reason Diamond stopped using Artemis on their tables smaller than 9 foot and went to Diamond Black rubber.
