Mark, What I can tell you about the Wilmslow 9th is that it's a seemingly innocuous drop shot cross a stream to a target green set on the start of the upslope on the far side, so it slopes down significantly from back to front. It is also slightly angled across the line, the axis being front left to back right and there are four greenside bunkers, two either side. It is generally two or three feet higher than the surrounding ground. On the tee you are largely unaware of the wind which is funnelled down the river valley at right angles to the direction of the shot. Escape from the bunkers is routine enough, but chipping from off the green is difficult, and from through the back of the green scary - you have to get the ball up onto the putting surface which runs away from you downhill towards the stream. Most people overclub leaving a testing downhill putt, which we invariably leave short, scared of trundling on into the stream. Although the putting surface is a sloping plane, it is difficult to ea the exact downhill line because it is also slightly tilted and we generally allow too much or too little break. What makes it all the more fun is that you know you are messing it up under the gaze of members who are enjoying their post-round drinks sitting in the big picture window of the mixed lounge with more than a little money likely to change hands as a result of the bets they made while you stood on the tee.
Of course there were lots of other 9th hole candidates but I'd decided I would do my bit for my home club, and I needed another par 3 at this stage in the round. I had contemplated the 9th at Beau Desert (a 270-yard par 4 across a decptive valley) but the 5th there is a real corker, driving across low ground to a fairway angled across the line right-to-left then climbing to a hilltop green which has a 3-level putting surface, highest in the middle - a sort of upside-down Biarritz, although not as extreme as Yale or N Berwick!
As Tommy pointed out there are so many other candidates in our area on B-list courses, although I must remind him that Bull Bay is in Wales - outside my brief. I did certainly consider the 6th at St Enodoc, but I'd got myself stymied over a par 3 somewhere at that stage of the round. It's a desperate process including this hle or that because you are then forced to eliminate other contenders.
