Thanks for posting the video of Ben's comments.
I have played Seminole several times, even in tournament conditions, and I think Ben's identification of the greenside bunker problem that his team addressed is right on. Seminole, being a wind swept course, found its difficulty or challenge in 3 areas. Speed of the greens was always very high, and thus difficult in wind conditions. The greens, being slightly crowned in many areas, would often repel good approach shots. The problem with that was that the bunkers surrounding most of the greens had steep faces, and as Ben pointed out, the width of the bunker meant that the ball would race off the green, down the steep slope of the bunker and then onto an upslope on the outside edge of the bunker. This made the recovery shot very very difficult even for accomplished players. Downslope bunker shot to elevated fast greens in windy conditions will run your score up quickly.
I was very pleased to see all that Ben described that was being changed at Seminole, and especially his identifying the problem with the bunker relationships to the crowned greens. By widening them out as he explained, the ball will have space to come to rest on the bottom of the bunker and make the recovery shot much more predictable.
I look forward to playing it next May. Great work Ben.
