I agree with Bobby. I take lessons, but I find that taking screen shots of slow motion videos of the pros' shots and then coming up with a document that talks about the things they do that make their shot effective and then copying them can make much more of a difference than just taking lessons, where you basically do the same drills everyday. Watching videos has greatly improved my ground strokes over the past few months. I'm able to get a wrist snap without hurting it, and its all due to the internet. My shots don't look exactly like the people I copy (no one's does), but there nothing wrong in copying from the best of the best. Which is what this thread was all about. Now stop arguing and bury the hatchet.
