The 14th and 15th, to me, are awful golf holes....but Matt Ward and I have already had this discussion and in fact, La Purisima was discussed in some detail in a thread about California public golf maybe 3 months ago.
Without trying to re-open that can of worms, and knowing full well that it might get opened for me, I will provide my basic opinions on the golf course:
-As far as California public golf goes, La Purisima is affordable and impressive - it occupies beautiful property
-The first time I played the course, I was blown away by it's quality
-The second, third, fourth, fifth, and sixth times I've played the course, I've thought less of it each time; I still think my first bullet point is true but I no longer believe the second one
-It is better than it's counterpart, Hunter Ranch, but the front at Hunter is better than the back at La Purisima - put the two front nines together and you've got a hell of a golf course
On to your specific thoughts (because Matt Ward would accuse me of being vague)
-100% agreement with you that the front nine is the better of the two, however the 17th hole is the best par 3 on the course.
-11 is to me one of the better holes on the back nine - absolutely
-14 is awful - any hole where a layup shot hit on a normal line (3 wood at those 125 yard trees) runs you through the fairway is going to not sit well with me. "Going for it" over the trees is not going for it at all if it's the only line you can play with anything other than a 4 iron. I do not like that hole
-15 to me may be one of the worst holes in the area - again, Matt Ward disagrees and that's fine, but the only redeeming virtue of that golf hole is the green setting and complex itself - it's an apt approach shot, but in that regard it may have been better as a 310 yard par 4 that favors a screaming fade. The tee shot and second shot are terrible. Which bunker are you drawing the ball over from the tee, and which tees are you playing? As I recall, your only choice off this tee is straight away with a club that will go less than 250 yards rolling downhill and the closer you hug to the left, the shorter your second shot.
-I do like the routing, I do like the variety, and I did place the course in my So. Cal top 10, but I believe it's an overrated underrated golf course...for so long it was a secret amongst folks and was worthy of more praise than it got...now it's a bit too talked about and too idealized by people making the journey from LA and I'm not sure it warrants the type of architectural praise that a Rustic or Barona gets. There are great holes (2, 4, 7, 9, 11, 17), there are overwhelmingly average holes (6, 12, 16) and there are terrible holes (14, 15, 18).
I'd choose La Purisima for an afternoon spent amongst friends, absolutely...it's a great spot and really a wonderful place to take in some of the good things in life...but if walking 18 holes solo, there are a few other courses on my list above it.
