George Bahto,
I think The Knoll contains some terrific template holes, perhaps even to the degree that some represent the ultimate evolution of some of the templates.
The 3rd hole, the Redan and the 13th hole, the Biarritz both have noticeable spines or contours within the putting surfaces.
I fell in love with both holes the first time I played them.
The 13th was always more of a challenge because it required a longer, more accurate shot, without the architecture correcting marginal shots, as a Redan can do.
I believe that automated irrigation systems ruined or diminished the architectural intent on Biarritzes.
With the basic footpad of a Biarritz being elevated, that footpad tended to be dryer, thus accomodating the running or low tee shot.
The moment automated irrigation systems were introduced it changed the play of the hole, making it far more aerial.
While it took a long, long while, I think clubs with Biarritzes finally came to the conclusion that the front tier and swale had to be mowed to tighter heights in order to restore the original architectural intent, in terms of playability.
When properly maintained, a Biarritz is a hole that's exciting, challenging and fun to play.
George, the thing about # 13 at The Knoll is that just getting on the back putting surface doesn't guarantee a par.
The contouring in the putting surface, call it a spine or a horseshoe like contour, makes two putting, when you're on the opposite side of the contour, very difficult, so, just hitting the green in regulation is just the begining of the examination.
