Yeah, we are spoiled today with "usually" level Diamonds with 1 piece slate.When i was first around good players/action guys i soon noticed that they all hit most shots at about the same speed and RARELY did they slo-roll one. They play on equipment that varies from great to pure shit and they can't take the chance of whitey rolling off.
A friend of mine slow rolls a lot.... I suggested to them to go find the shittiest Valley you can in the filthiest place and change your game to work on that table. That will make you a better player on the good equipment.
