You know who my first real Mentor was. Before we considered ourselves true friends I decided to take his lesson course. I think it was $100 for 5 1hr lessons. Of course the lessons went longer, as he loved to talk and teach.
Lesson one he says at the beginning "You're a decent player, except for your Stance, Bridge, and Stroke!!
He's the man right? So I go with the instruction. I went from a below average player to...
Well, lets say we had to lower the X Axis to find where I could be Plotted.
Going off the graph isn't always a good thing.
At any rate I was a believer. After all he received instruction from some pretty significant players who received information from some of the greatest ever. At any rate it took me maybe 90days to find the starting line again. So yes, for sure a lesson can knock you down.
I'm with you on everything but the development of a permanent hitch. Without the facts I'd suspect that's self induced trying to overcome another hitch and the reason the player sought instruction.
I've taken lessons from several people. These days I think the only reason is to learn for learning sake, from someone with special talent in some area. I'd like to spend time with Stan or Geno, just to hear what they have to say. I like simply acquiring knowledge. I kick myself for not taking up Hal's offer to come to his house for a few days. What an opportunity. Not just his aiming.. You know
Anyway as far as Advanced and Pro players. I think (guessing) It comes back to fundamentals. Unless there's some breakthrough game strategy or something, Top players have the skills and knowledge of the game(s) and the Cue Ball.
They don't need lessons! Except..
Sometimes there's a slump and a skilled coach can put their eyes on that situation. Evaluate, test a theory, and then suggest a solution(s). Then evaluate again.
When there's a slump with a Pro Level player, I have to think it's coming from something fundamental. They already know the game(s) and cue action.
The mental can mess up mechanics and vise versa.
You are a pretty capable 3C player, no doubt.
The thing about a hitch is that if you truly believe what you’ve paid for it’s tough to let that go.
