3). No doubt the ocean holes are among the finest you can play. Hard to beat the combo of the 6th, 7th and 8th as the best par-5, par-3 and par-4 combo for three consecutive holes anywhere. No doubt there may be candidates for debate but few will really push the trio I mentioned to the max.
Matt, I'm not sure if you mean the order has to be exact, namely a par 5 followed by a par 3 followed by a par 4. However, if you simply mean one of each par in a three hole stretch, I'd say Merion East 3,4 and 5 surpasses Pebble Beach 6,7 and 8 rather handily. Pine Valley's 14,15 and 16 are close enough to call even.
