I’ve got two projects in planning where the client has moved the clubhouse site on me, so what was my 18th hole is now the opener, and the old 17th becomes the 18th. (The new course at Sand Valley is one of these.)
Neither is built yet, of course, so it’s fairly simple to think about the difficulty of the hazards and green contours in light of the new order. And I might not build the back tee as far back for the new opener as I would have for the finisher. I think it’s those sorts of adjustments, more than the general length, that really determine whether the hole is a good opener.
