It is a big part of why I preffer a GC. It is like I said above, a pocket should play consistently. Diamonds are inconsistent on ball pocketing in the corners dependent on object ball distance from the rail. The pockets on a Diamond are actually pretty generous on balls positioned in the center of the table off the rails, and on the shots on the rail one must suddenly aim at the outside horn and with a slower speed. Unless you are forced to hit it hard for shape and then you better hit an accurate pot that would go in on a snooker pocket from that same angle. Pockets should not actually encourage rolling balls in because they spit out everything but a perfectly hit ball down the rail if it has any pace at all.
Diamonds in this way play more like a 2-shot table, or any table that has round snooker cut pockets. The shots become more difficult to make down the rail and this actually affects strategy and the way you need to hit the ball. I have played great on Diamond tables but it took a whole new strategy and reworking of my game. There are "tricks" to making shots on a Diamond, while the Gold Crown really has no "tricks", it is fairly neutral to speed you hit the ball and realtively neutral to cheating the pocket to either side. The Diamond takes one side of cheating a pocket clear out of the equation on a ball near the rail, you spend all day cinching balls instead of stroking them. You start focusing alot more on angles you leave yourself and shelf the draw, follow, and cueball moves you might use the closer and closer that object ball gets to a rail.
On a Gold Crown you still have the same margin of error to a corner no matter how close to the rail the object ball is. A straight shot down the rail with the cueball 2 feet from the object ball and the object ball 3 feet from the corner is about as tough as a straight shot on a object ball in the center of the table with the cueball 2 feet away from the object ball and the object ball 3 feet from the corner.
