You ever tried internet lessons? They can be a pain to load but you're already doing that nicely. Lots of sun for high speed. Never any snow... Man Im jealous.
Emailing or posting a video of your swing for an instructor to breakdown. I believe both Ted and Jeff offer this service. I know Ted does for sure 'cause he helped me out quite a bit last winter. Id send him videos from the indoor golf dome here in Toronto..........he'd send me back an analysis with lines, angles drawn overtop of it, split screens etc. Its not as good as a face to face of course but its the next best thing.
You know with somebody like one of Lynns guys doing it ............the swing advice is bang on, precise. Ted wasnt teaching method over the net or anything it was more like ..."OK look at this right here...see that little bit of Steering there...well that was caused by this (running out of right arm or whatever). Its a compensation, so what I want you to do is ......"
Sort of like getting a physical done at the Mayo clinic or something. But without the gowns and blood work.
