Ok. I believe standard Diamond shelf depth is 2.0" with 4 7/8" opening. The pro cut is 4.5" opening. So a 1.5" depth would play a little easier, but average when compared to any other table. Not real tough. It makes it so when you freeze a ball to the inside facing of the pocket, as deep as it'll go without dropping in, 40% of the ball (0.9") will be be sticking out if you sight straight down the cushion. The table probably isn't going to play a whole lot tougher, even after the cloth wears a bit and the balls quit sliding so much. A player of your caliber could handle it regardless of whether it plays tougher, so I doubt you'll find many balls hanging up in the pockets.
I have a 4X8 diamond with easy pockets. They are 4.5" but the shelf depth is only 1 inch. I wish they were 1.5 or even 1.75. My old 9ft Brunswick had 4 3/8" pockets, facing angle of 138°, and shelf depth of 1.5". It played super tough, even compared to any diamond table I've played on. It was that 138° angle versus 140 or 141.
Anyhow I would love to have your table!! Very sweet setup, and nice room.
