By the time we played Pacific recently (me on the bag, summer tailwind out of the north) I had the trust of my player and simply handed him his 130 yard club.....from 180 yards. He had about 15 feet left, so as we were walking down the fairway I asked, "would you have hit that club if I told you you were 180 to the flag?" The answer of course was "No!" and therein lies the LAST challenge of 18 at Pac.
The tee shot is deceptive in the accuracy required. Balls can bound both left and right into trouble. The 2nd shot then over or past the dune on the left is VERY directionally exacting (with a sloping fairway willing to lead balls into trouble right), leaving an approach shot to the green for which yardage seems almost irrelevant.
Suffice it to say, the approach shot is links golf at its best, with the sloping runway approaching the green on the left from 40 yards out used as the landing area and the ramp between the two bunkers long / left as a backstop if necessary.
PHENOMENAL finishing hole!
