Mike, many have already tried to get lessons from Efren, he laughs, usually says he can't do that, and then directs them to his "instructor".
You sound like you are looking for that "magic bullet" that will propel you to the next level. Which for you, would be pro, from my understanding of your play. Have you ever considered the fact that with your current ability, you know enough now to go pro? The thing holding you back, and I say this without even seeing you play, is not your ability to do pretty much what ever you intend to on the table, but your inability to sustain it for longer periods of time.
In your other thread, you hit on one of those things, sheer laziness. Something we all suffer from at at times. Believe it or not, that is the main thing. After that, it's keeping your head straight. Again, that's where the laziness comes in. You have head your head straight plenty enough times to be able to do it. So have I. Problem is, we get going good, then get a little lackadaisical, and start to let sloppiness creep in. Eventually, it bites us. A little lazy or sloppy on making the shot, we miss. Same thing with position play, a little sloppy, and we are now out of line when there was no reason to get out of line to start with. We do the same things the pros do, just not as consistently. That's what the whole game is about, maintaining consistency.
Now, with that said, at the very top levels, the pros have much better cue ball control than most. I believe that's largely a part of how the subconscious works in each of us.
You want to be a top pro, good luck. You just want to get to the next level, and maybe the one after that, you already know what to do to get there. You just have to do it. It takes a lot of time, and hard work to break old habits.
Mike, with the above said, as long as you have been on here, I am assuming that you have availed yourself of all the knowledge that already is available from this site and it's associated links to related sites. If you haven't, then yes, a pro can probably show you something that you don't already know. But, then, that would go back to the lazy part of not utilizing what you already have access to.
