One of the things I would like to see in your ball comparison videos is both bolls being thrown on exactly the same line! Showing nothing but strikes on diffent lines is a good look, but a better look for me would be one striking on its best line and the other thrown on the exact same line, then vice versa, whether they both strike or not. I'd get a better read on the diffent balls thrown on the same line!
Does that make any sense to you?
