I'm kind of in the same boat. For certain situations I think it would be the bees knees. Yes it saves you from re-racking.
But the break is SO much more than squatting the CB. This isn't knocking the device. Again, good for practicing certain aspects.
I'm not a great player but I'm flabbergasted that players don't know where balls trend on the break. Even really good players. You can manipulate the general area where the balls end up by changing CB location, speed and spin. It's all about observing. Even Dr. Dave has the diagram where balls trend. If you've ever replaced cloth you can see the track lines on the slate.
To me, this aspect is way more important than squatting the CB. Again, I'm not great at this game, but even for me it's dead easy to squat a CB. I'm a nobody but I can look at the numbers or colors of a rack and know where and how to break from for good results. It's not some analysis either, it's mainly from feel and paying close attention to the break for a month or two. It's a skill that is within anyone's grasp if they pay any attention and train pattern recognition. I'm doing this stuff by "feel" without any real conscious thought.
I may be dead wrong, maybe I have a touch of the 'tism or something but anyone near or over 500FR should know this stuff. The break isn't random. There should be about half a dozen to a dozen breaks you can use to get favorable results on the first 4 or so balls. The rest is gravy. Yes, there are more variations in where balls can go than a dozen but you should only need the first 3 or so balls to be able to get shape to run out.
I should write a booklet on it but I'm much too lazy.
