Yes the experience is pervasive. However, as it would appear with all things GCA, any uniform presentation maybe just as bad or ill conceived.
Also, there is a significant difference in 1-1.5 inch rough, fronting these bunkers, and a 3-4 inch cut. If the course is truely F&F the 1-1.5 inch cut would have little impact on a balls forward momentum, adding to the excitment that unpredictable outcomes provide. Opposed, to the 3-4 in cut that's irredescient green from over-watering and the almost assured fact that the ball stopped short, save for the aerial directly in the bunker.
Someday I hope to read the definitive maintenance meld chapter on this subject. Somehow, I suspect that a random use of both styles, would be more in-keeping with the nature of the sport. But I could be biased towards the unpredicatble, cause I know I am biased against making the sport easier in any fashion, for any level of player.
