Having played Valhalla a few times in real life, it would be a great addition if it were to be a full stroke play course. Great layout with a lot of options on your tee shots, the greens have multiple tiers to allow for great pin placements. Long and short Par 3's and split fairway on one par 5. It is in my home state so wishful thinking on my part to want this course as stroke play.
This Jack Nicklaus design has some great history with the PGA returning for its second time, The Senior PGA Championship and the Ryder Cup. It would be another star in the WGT crown if made a stroke play course imo.
Enough with the CTTH as it does very little to excite me. Playing CTTH one time in a month is one time too much imo. To each his own I guess.
