Last year at the Washington State Mid-Am, we played GS from the tips on most of the holes (so 7050ish yards) with greens rolling at 11+. At those green speeds, the greens play very different than at their regular 8 (I have played them at 8 a half dozen times). And those contours have negligible impact on strategy at 8, but at 11 they feed the ball away from the hole; long distances from holes on those huge greens. Therefore, you are thinking about the pin position on the tee box, because you know that you can't get at certain pins from certain places in the fairway; at least the places I knew I was going to be. Because of the firm and fast greens, the only way to get to some hole locations is to bounce the ball onto the green; much like links courses in Scotland. But when they put the pins at the edges of the contours that do exist, it is very hard to get near the pin no matter what you do. That places a premium on lag putting from 40-60 feet which we faced a lot under the fast green speeds and because of the longer clubs required to hit 470 yard par fours and 225 yard par threes; let's be honest, you don't have a lot of spin on the club you are hitting from 200+ yards unless you are a tour pro, so the ball is going to be rolling on the fairway or on the green, and at 11 those contours became very evident.
Tom Doak is correct, a lot of the short game is less imaginative at GS, because you are typically faced with either of two shots: in a bunker, or from a tight lie to a green that is on the same level as your ball; no mounds, hillocks or raised greens like Scottish/Irish links courses which requires a different type of shot not found at GS. You can leave your 60 degree at home; not much need for it around the greens.
Honestly, having played the course when it was set-up to test better players, I preferred the greens at the faster speeds. The 7000+ distance was too long for this 54 year old, 5 handicap, but I did like the faster greens; which is not something I typically say; typically I prefer something on the 8-9 range for most courses, but I thought the faster greens at GS enhanced the course because it made the greens more interesting and enhanced the strategy of the course by making you worry about the pin on the tee box.
