Tom Doak,
I can understand why the club may not wish to mess with the 11th green and approach. Perhaps mowing the approach long will do the trick. The greens were not very fast (well under 10', I think) when we played, and we probably spent 20-25 minutes on that hole each time trying to hole out (no practicing). I damned near chipped in from 25' for birdie in my first round and ended up making 7.
I would think that you could raise the front 3" to 4", feathering the material up the slope 20' to 30', and down the slope at least on the right half of the fairway to still enable the run-up shot. Of course, you are the architect and know the hole much better than me.
Andrew,
In my opinion, #10 is not particularly challenging off the tee, on the second shot, or the approach. It will play with the wind much of the time and it is reachable in two for even a medium short hitter. Conceivably, if one is on the back of the green and the pin is on the front, the putting can be difficult. With a chip or short approach on the third shot, hitting the cupped section of the green should not be a problem.
CPC greens typically have considerable back (high) to front slope, some tiers, and are often perched on hillsides. With the wind, bunkering, and relatively small to middle size greens, getting the ball on the proper level can be very tough. Even greens 14, 15, and 18, described by some as relatively flat, are very demanding from above the hole and on the high side. Running in the 8' - 9' range with moderate wind, the greens are manageable.
I think that #14 is one of the best mid-lenght par fours I've played. If you manage to hit the opening of the bottleneck, probably with a fairway wood, the second shot might be with a middle to short iron to a smallish, well guarded green running from left to right. Over-compensate for the wind and miss left, and the bunker or chip shot is next to impossible. Leave the approach hanging into the crosswind, and you can end up right of the green, maybe behind a tree. Unless you are below the hole and putting straight up the slope, best of luck.
#15 has a free flow green (deep left, narrower right) with some smallish tiers. Though normally requiring a W to 8 iron approach, the wind and the awesome surroundings make hitting the proper section of the green difficult. Two putts from middle/back left to short right can be very good.
#18 has a perched green and it is difficult to hit the right club to get the ball on the cupped area. The green slope, as I recall, is considerable from back to front, with some from right to left. It was there where I struck a 3' putt to a hole cut on the middle left of the green just as we read it and never even touched the edge. My miss for a par flipped the bets, leaving my partner (our host) wondering why he hadn't chosen more wisely.
