Johnny,
Everyone has trouble taking their swing from the range to the course. Everybody. I've seen Tiger nearly hit every flag on the range for an hour and then not find the course with a single swing. When he finished he said that he hit it ok, just didn't make any putts. Its just a different mindset with those guys. We EXPECT to play well and take it to the course, they roll with the punches. Enjoy the process and learn your misses. Overdo your corrections. Watch guys like Graeme McDowell (who also fights underplane issues) practice. Every swing he makes is an exaggeration, over the top move (a la Corey Pavin) even though his swing looks nothing like that. He's hoping to be somewhere in the middle. If you are hitting it good on the range, you are half way there.
If that doesn't work, you've always got the O's, Strohs and Natty Boh's hun.
