Adrian,
The revisions you have described sound a little like my initial lunchtime sketch before the one I posted. I went away from it because though I dont mind a par 3 to finish, or playing over tee shot over a green, I figured both together was a bit tricky and tried to come up with something else from the amatuer designers point of view.
From Sean's initial fear about the impact on the club, I think we have all managed to prove that there is some scope for retaining WHGC and its Colt heritage in some form, and its not a total death of the club. Obviously the matter of compensation, programme of both the HS2 and clubs works, keeping a short version of the course open during the works, and also any buffer zone along the tracks or impact of the construction are also an issue, as is the visual and sound impact of the line, all are big factors. But as I said, there is potential for some kind of new routing and so the club wouldn't have to move or die?
To be honest, I love the fact that Ben had a crack at this (promting me and Matt to have a go) and has at several other courses in the past. Sure at times they are a 2D exercise and we all recognise that golf course design is not as simple as that, but they are fun and should be encouraged. We can't spend all our time arguing of who designed M****n, the use of carts or looking at Natalie Gulbis videos...
Cheers,
James
