OK, I get what you are saying. I agree that making it look easy is what it is all about.
Let me ask you something else while I've got your attention. I was watching a long run of yours. I don't recall if it is from your CD (which you sent me a copy of a couple of years ago) or from Youtube. I think it was the CD. Anyway, I don't remember if you recommended this outright or if it was something I just saw. You were playing to have 2 key balls near each other, and not just one set up ball and one key ball. The idea, and I think you said it, is that if you have two balls in a good location to be key balls, having two balls there allows you to be more precise in where you can leave the cue ball for the break shot. I've been playing with this in mind and I think it has helped a lot on some racks. Did I understand you right?
