Mark, you raise a great point. Personally, I feel the people who are critical of RMW owing to the lack of a long par 5 overstate the way in which they play them. I play there consistently with a long driving, long hitting member off 2. Sure he sometimes has 7 iron into 2, but he has lots of club in hand into 12. Are the golfers who suggest there's no par 5 out there all getting through 2,4,12 and 15 in -4? Are they all hitting short iron into all 4? I seriously doubt it.
Chris, I feel the lay-ups at 2 and 4 are really interesting, particularly with some pins. 12 not so much, and 15 less so, but they still require thought, and placement. And, I think there's a little more variation in compass points to which the par 5 approaches are hit than you're suggesting.
And, didn't MacKenzie say something even in one of his books about good long holes being three shot propositions for average players, but good two shot holes for accompliched players? Maybe RM is playing as he envisioned?
