darktone: The holes with the huge drop in elevation throw me off. Is there a rule of thumb for calculating yardage on holes like this?
I take a bit of a simpler approach as posted above. I just calculate about -3 yards for about every -10 feet of elevation.* And if the wind is behind me, I use backspin; if it's into the wind I use top spin. The killer are the crosswinds.
On the 9th hole of Chambers, if there's a left to right wind, I find that I have to aim well to the left of the pin. As the person above notes, the ball is the air for quite some time, which means the wind has a huge effect. In any case, if I recall correctly, I play that tee shot at about 180 yards from the tips, which a full shot with my 6 iron.
*By the way, 3 yards for every 10 feet works about the same as the formula posted above. But I think it's easier to calculate in one's head. :-)
