Tom,
I believe our research confirmed the front and swale at Yale #9 was always putting surface - and even a purist like Uncle George always maintained if C.B and Raynor were around today, they would approve of converting the run-up area on Biarritz holes to putting surface.
My memory is fuzzy, but was the Biarritz at Fishers also converted? I think that is the most difficult (and exacting) one I have ever played - wind or no wind.
Given the insane distance the young gunners pound the ball - and the elevation of their shots - I wonder whether the Biarritz has been reduced to a charming anachronism. The Doak Biarritz, maybe not, because of the firmness of the green and added complexity of an irregular swale, but the last trip around Piping Rock I played with a kid who pulled out a 6-iron and hit a towering shot that landed and stuck right next to the back pin.
I cut a 3-wood and managed to run it through the swale, but it never even occurred to this kid to play the hole like I did. It reminds me of the difference between my strategy to play the Redan at Shinnecock and Freddie Couples. I try to sneak a 4-iron up the ramp and hope it takes a hard left turn and totters down to the back pin.
Freddie took a 7-iron, hit it so high it grazed off God's undercarriage - and dropped it out of the sky to four feet . . . . . . I think at this point, for the highest levels of play, the Redan needs to be 250 yards and the Biarritz the length of a drivable par-4.
BTW, Harbottle's Redan at Stevenson Ranch was a thing of beauty . . . . people forget his original concept was to create a slightly modernized NGLA. To that extent, I loved it - even with all the obvious artificiality. The Alps was ballsy enough it looked like something Mike Strantz would have built. We had a KP there, many years ago - I've still got our group photo . . . . I wish this DG could go back in time - if only to have one last beer with Brains Goodale and Huntley.
