I'm not sure if Brad is suggesting the retro for the benefit of the spirit of the players or the spirit of the fans. I believe that Chris B., is on track to the nearest situation that could be comparable. The only other reasonable retro thing that could functionally be viable is that the R&A require a competition ball during the Open.
Making these golfers suddenly switch for one week to old clubs would be futile and screw up their finely tuned swings for perhaps weeks to come. Why embarrass them just to get some jollies on a nostalgia trip?
Unlike hockey, that has truly physically demanding and strength-endurance requirements, with basic stick handling fundamentals and skating technique that can go from surface to surface (even regular league rink ice varies greatly) golfers can't adjust to such radical venue and environmental inconsistancy so well as top hockey players. Hell, several top golfers skip the Open because they don't like the more variable and usually harsh conditions of the links venues.
Maybe Tiger can take a rap in the mouth, spit out a chicklet and then get on the next tee and hit a great shaped shot, because he falls in that real athletic mentality mold, but I don't see most of the tour players having that 'old time hockey' spirit. What is 'old time golf' spirit to the players? A hot day, wooden clubs, carry your bag, and smoke ciggies?
As for the fans sitting in the stadium for hockey... this was in Buffalo, not Augusta!!!
People there are acustom to winter rugged sports along with rugged spectating. It is as different as a cheese steak or brat and beer to a pimento sandwich and coke. What is going to make a golf fan feel tough, rugged, full of old time spirit? Can you imagine a pampered golfer like Sergio being forced to hit a persimmon as a challenge to his manhood? Does that really get the golf fan's juices going? The closest we have come to fun spectating in the sense of watching golfers toughing it out is something like the last President's cup, where Woody took a dunk.
We hockey fan's know the definition of "old time hockey" and get the loose connection of their tough guy hockey heros going retro to a venue that reminds them of the pond hockey of their youth. Golfers and golf fans don't have a comparable, IMHO.
