about 10 years ago i was in a similar posish...got myself a bunch of lessons at GOLFTECH and would watch the film and analyze all my angles and do all the recommended drills to fix this, that and the other thing, etc. etc. Anyway, after like a year of that I still wasn't really getting any better. Then one day i was at the driving range, frustrated with my lack of progress, and noticed that the driving range pro offered lessons. Dude was this fat good ol' boy who probably drank 1/5 of Jack just to get out of bed in the morning. Anyway after 2 lessons with him my swing and my game were like a million percent better.
IDK if that's because at GOLFTECH you're hitting into a net and relying on the technology to tell you how far you would have hit your ball. off of an astroturf pad. And then there's being at the driving range and actually seeing where the ball goes for real, and maybe those 2 things don't always match.
It was kinda funny b/c part of the package i bought with GOLFTECH included a playing lesson where you go play a round with your instructor. By the time we got it scheduled I had already taken a few lessons from the driving range pro, so it was just kinda funny, hearing my GOLFTECH pro trying to give me some pointers when we're out playing and the whole time i'm thinking to myself "you get no credit for any of this"
