In reading Macan's assessment of courses in SF in 1926, It struck me how penal he credited sand traps to be. In 1926 the Sand Wedge had not been invented. And, if playing with clubs like I have where my most lofted club is a Mashie Niblick with a thin little sole and tiny bounce, if any, getting out of the sand is a bitch, at least when using modern blasting technique.
Maybe a Niblick played differently would change the equation, but as it stands now for me, a deep green side bunker with 1920's equipment is a bad place, a very bad place.
I think most of us kinda smirk at Macan talking about zig zagging around w/o crossing a bunker, but if you replaced every club with significant bounce (say 6 percent) with low or no bounce clubs, would it change how you play around those cavernous bunkers?
