The other thing a lot of people aren't seeing here who haven't taken this to the table is that although the 6 is pretty straight it's not so straight that you can put a stop shot on it and hold for the 7 in it's tracks. It will stun toward the rail unless you really baby it and we all know not to do that. Leaving you longer from the 7 with the cue ball than you will like to put a good follow stroke on. And very likely off line left or right too.That's actually the best aspect of that pattern. Versatility.... Regardless if you come up a little short or a little long, it's still the same shot with a little tweak with the same type of spin. ...and the gap between short/long is largest of all your options.
This highlights the problem with all the other options.., the lack of versatility. If you blow passed or fall short of your intended shape on the 7, you now need to hope you get good enough on your alternative pockets to recover with a high precentage.
Try it you will hate it.
