Is there an easy way TL? Yes, there is. You need 500 rounds as Legend (to start), then as many rounds as it takes to drop to 59.999... For me, not being the greatest at hitting the ding, it was another 361 rounds. Rememer, after you play 500 rounds you are locked in. Any bad score is dismissed and any good round replaces the bad rounds (starting with your worst score first). Also, if you play 9 holes, WGT doubles your score so that a 29 becomes a 58.
What's the "easy way" that I took? First, become a member of a good Country Club. Next, get good at a single course's front or back 9. My favorite front 9 (and everyboy elses) is Bethpage. Eventually, I (soon you) became a TL.
It doesn't hurt to have the best equipment and balls WGT offers.
Good luck in your quest. I'm rooting for you!
