Hmm,
The way the 15th green at CP used to twist around, I would have figured it played a little different every day.
As to strategy, Ross wrote that they could be a bit tougher tests of precision, since the ball was on the tee, and in fact, many par 3's are just that - straightforward shots to well protected greens.
I think CBMac had the better idea for par 3's - use them for "concept shots" like the Redan, Eden, Biaritz, and of course, his short was similar to Ross' idea on precision. A concept shot makes the hole interesting in option of tee shot related strategy.
