Wow - the reasons for lengthening still escape me - increase in rating/difficulty?
#2 - you gotta be kidding me. Extending this hole makes a tough second hole beyond difficult. And when considering the relative ease of #1 and short #3, it would really feel out of place.
Isn't there a general rule that length is best added to long holes, not short ones?
And, I don't follow the logic that if #1 and #3 are easy, #2 should be nice and gentle as well. That doesn't really make any sense.
It's not like #2 is ridiculous, anyway. It's 457, downhill, with a fairway that's almost impossible to miss. I forget if I hit 7- or 8-iron into that green. I held the green from a bad angle. Isn't that a clear indication that the hole actually needs additional length, at least as an occasional option?
