WOW, when you miss a point, you really miss. "the bottom of the totem pole" reference was referring to weaker players. And not all things being sold have to be marketed to new player or even players with weak strokes. IF folks think they are good enough, or have the skills to move up, that is their choice to make. But again, you can't sell something based on only what the low level guy is doing.
And you know what, I think any pool player knows they are only as good as their stroke, and if they don't know that, mabye they want to get the corrected. But my goodness, I really hate when I get a pool book on advanced instruction and it's talking about how to make a bridge?? So, yeah, folks do it all the time. And if some folks don't want to, so be it, that' their choice.
And actually, I am an advanced instructor, and NOBODY can pay me just to learn how to "aim". Everyone gets the same first lesson, and it depends how "good" you are as to how far we advance in that lesson. Some folks have rock solid mechanics, or just need small tweak here and there. We'll get farther along in the first 2 hours than most others.
And I've spent the first 2 hours just on someone's stance, bridge, grip and teaching the how to hit center ball, 2 hours because they could not do it. Once the bridge was good, there went the elbow, once the elbow was fine, there went the wrist, I felt like the kid putting his finger in the wall at the dike.
So, yeah, we are arguing about the same things. Sure, everyone should have their strokes evaluated, but folks don't want to "pay" for such things, or they don't believe they have a problem. Nobody can "fix" that, so if they want to buy aiming DVD's or whatever, so what, i'd rather have good aim and below avg stroke, then below avg stroke and terrible aim, no ??
And yep,, I have a 100% money back guarantee on everything I sell and every lesson I've given. After 12 years, and close to a 400 lessons, and if you are not 100% satisfied with the lesson, you don't pay. I have the same policy with baseball hitting instruction, but i charge and get TWICE as much for baseball as I do pool, and the same deal, if parents are not happy, don't pay me. Nobody has taken that route yet, but I"m sure it will happen one day, and I'll won't take it personal, if they didn't get what they wanted, they should not have to pay.
