Paul,
I agree there needs to be an adjustment in the attitude towards the Traditional #'s 70, 71,72, & 73 par for the course courses. Focusing on a traditional number is limiting. While also encouraging the bigger and bigger sites, longer walks, bigger budgets etc. Basically the direction we're on.
Building shorter(lower par) more interesting courses seems to be how one should comprehensively test the better players, While keeping the handicap player interested and more involved as a player and a fan. Who wouldn't want to see an Open Championship at Painswick with Par set at 40. I wonder if +10 would win?
It's a natural progression too, since there's only been bitching about the distances gained, throughout the history of the sport, due to technological & educational advances. No regulatory action, though every great designer warned "them" each and every era. Why do you think they ignored the Architects?
