Ah, Bobby, another gem, another one of my all-time best courses, always enjoy going out to one of your courses and playing a round. I know I don't notice a lot of the nuance others do, but imho if you want to go out and have a good, fair test of your game, play a round at Whistling Straits - Bobby Bolin style!

Just found out that there is a 4th version of this course : had to play it right away !
I did not play the 2019 version but I did play the 2009 and the following comments are simply a copy and paste :

What a masterpiece !
Teeing off from the first hole downhill to the green, you know you are going to have a tough time staying out of all the bunkers spread around the course.
Undulated fairways, doglegs, cliffhanger greens, blind shots : hard to choose a favorite hole among all the spectacular ones : 3,5,7,10,17 ?
Bobby Bolin did a great job improving this course every year and the only way for you to see the results is to download it !

P.S. I am still frustrated to find out why sometimes the color of the water is perfect (sea) and why sometimes the ponds & creeks look so grainy. I just finished playing Leopard Creek and I can't comment on the course as the water over there looks like... the leopard's skin !
Gunpower61 told me that designers have found a way around to include a little part of ocean into them but, apparently, it was not applied to this course (at least on my PC...).
Playing TW07 might also be part of the problem as some courses might not be compatible with my graphic card... Too bad !
