We can walk into a ski shop and tell the salesperson that, for example, our skis won't hold and edge, and the salesman, who has never seen us ski, will tell us that such and such a ski will hold an edge better than what we have, which will probably be right and may or may not solve the problem but probably won't. And obviously an instructor can always find something wrong with our technique, and fixing that may solve our problem--but it definitely won't be right away because it can takes weeks, or months, or even years to correct bad habits and learn new techniques. It is tempting to hope that a new pair of boots or skis or boot and binding work will fix our problem right away. But IMO the place to start is with a lesson--if the instructor feels that all the right movements are being made and the problem is gear related, then you go to the fitter or the ski shop. So I stand by my advice. I don't see anywhere in either of the op's posts where he says that his problems were analyzed by an instructor.
The OP's alignment issues aren't made up and are explained somewhat in this thread http://www.epicski.com/t/127502/is-my-leg-length-discrepancy-causing-my-ski-challenges#post_1723880
If an instructor works with someone to correct something that should be taken care of in the boot shop, once it is taken care of, the instructor will then have to replace that with proper technique or at least better/different technique. It's a great business model but expensive for the student.
I'm not sure the value of someone that knows how to ski, taking more lessons when at least part of the problem is caused by something lessons can't fix. The best you can hope for out of that is how to compensate or if the instructor understand movement analysis and alignment well enough, somewhere in there feedback that is something to the effect of, "you need to get boot work done."
One of the top complaints of instructors is most of the students are in crappy rental gear that doesn't fit right and boots too big (if their own). You are limiting yourself and the level of instruction. Before I got my shim, the only way I could get on my inside edge was to roll my right knee inboard. How is skiing in an A frame better? A simple shim made a huge difference.
With 3/8" leg length discrepancy, how can there not be an alignment issue? Once the boots are aligned, he should get lessons because all the boot alignment is going to do is rule out the need for a boot alignment.
Good alignment allows you to ski better. It doesn't make you ski better. Bad alignment does the opposite.
