Paul,
I'd say it works least on par 3s and more on the 4s and 5s. Consider feature location, and green contouring and the placement of shots that set up one's arrival become more strategic. Please remember that I believe there is a huge difference between tactics and strategies. Par threes only give the player the teeing area by which to choose strategy where as a four or five par present the entire playing area. High or low, cut or draw, knock down full etc... are tactics in my mind that react to the perpendicular nature of features where strategies react to those that present more parallel conditions, such as central spines. I’m probably not doing a good job of describing my thought here, but that’s OK. After a routing is done, you’re left to make the best hole that fits within that corridor and the green sites impact on the strategic nature of the hole is of exponential import to that of the tee and its contouring effects all of the fairway development and tee sets, as a result the design post routing is dictated by the green site, in my opinion.
Hope that helps.
