Phil,
I first played Firestone in the late 60's and as recently as a few weeks ago.
The ball, thanks to the ball and the modern driver, goes straighter and farther, yet, the course remains fairly static, unable to defend itself, without resorting to extremes. Maintaining the fairways by cross cutting them produces even more roll.
It's apparent to all but the most obtuse that a tournament ball needs to be introduced and that all woods/metals be subject to COR and driver head size be reduced.
I know # 16 plays downhill, but, when guys are hitting medium irons into that green from about 647, there's something really wrong goin on here.
