Kyle,
Our approach at Angels was a bit more complex and not limited to confronting length alone. One of our major premises in design was that we would 'punish the greedy not the needy'. By that I mean that those who failed to examine the construction or features of a hole and just bomb for the center of the fairway find themselves very challenged with their approach shots. In some cases the ridges also flip the intuitive assumption to play away from the pin to 'open up the green' for an appoach. On the tenth for example the player must favor the pin side to avoid or utilize the greens central ridge. We do keep greens very firm to counter the low spin ball. When the areas of the green that go away from the players line of approach compound this condition the mindset of just throwing darts at the pin can get you in trouble very quickly. Back to the tenth as the elavation of the approach shot increase the influence of the spine increases by virtue of deflection. Now I know someone will say a wedge is easier to stop than a six iron on the green, but in several instances around the course the player left with a 170 yard shot will consider the ground shot by virtue of the likely hood of success versus throwing one up there by air. A number of our greens also curved tiers whose central edge acts as a deflective spine in the greens internal contouring. Four, eight, nine, thirteen, fourteen and seventeen all do this to various levels. I think you can get and idea from the hole drawing on the MHC. Those topo lines represent significant contouring.
Hope that helps!
Cheers!
