Noel,
I know what you mean. It seems like it's always on the front half. I'm sure Scott and Peter would love to use the back half of the green more often, but it's probably a pace-of-play issue. I'm just guessing, but it could add five minutes to that hole on what is already a tee where groups back-up.
We definitely use the back half for Sunday's third round of the Macdonald Cup. It's amazing how many of the college players flail it right into the hillside. When that was thicker and covered with moss, balls could bury and get lost. I know Scott is very eager to expand that surface in the back. It's certainly on his punchlist and I do look forward to the day when we make that less "special occasion" and more regular occasion. The beauty is for most people, it will still be a wood and they can hit low, drawing shots that run through the swale.
