Michael:
I am not sure what you mean, but there is no bunker linking 4 and 6 green (there is a new tee box shared by 4 and 8 though). 6 green is all by itself and, while it was a difficult hole before, now it is a beast. Previously, if you hit a perfect 3wd/driver, you would have about 150-170 or so into the green over the creek. I got to play it a few weeks ago, hit a mediocre drive and 2nd shot was to the edge of the fairway. I had over 200 in to the green from there. Nice par 4.
Also, no new tee boxes on 2 & 18 and 15 is a couple of years old now.
I like a lot of the changes, but the greens on 8 and 16 are pretty severe. With all the trees gone, 16 has a completely different look.
