All good points. Good to know the angle is better from the right.
Measuring it on Google Earth, it's possible the right side was actually more like an additional 40-50 yards of carry (if we measure from where the left-side fairway used to begin, before they added the approx 20 yards of rough that starts it off now). So possibly something like a 180-yard carry versus a 140-yard carry from the back of the original tee. That's a good poke in 1920, and a fairly daunting shot if the fairway did indeed fall off hard toward the trees.
Pretty fascinating discussion. Was it too easy, or too challenging, or maybe too hard to maintain, or simply too out of place compared to the rest of the design? Hope there's a definitive answer out there.
