If it's driver+wedge for the longhitter, then how can it be a great hole? Certainly it seems quite boring for the longhitter. And how could a hole, that can be played in two shots like that, carry any strategic interest for the average hitter?
So, why would anyone want to build a hole like that and then complain that he has to call it a par 5 for "Top 100" reasons? Get rid of that hole and build two interesting holes instead, you'll get a par of 6 or 7 out of the same acreage and a much better course to boot
I'm not sure whether you are referencing the Gulph Mills hole mentioned above [driver-wedge] or my routing in California, but I'll answer your questions and comment on your proposed solution.
1) A hole can be great even if it's driver-wedge. The fact that pros are able to hit driver-wedge on a short par-5 nowadays isn't so great.
2) There can be all sorts of stuff going on for the shorter hitter, that the longer hitter ignores. Too much of that is a bad thing, but it's easy to generate interest for shorter hitters.
3) You're the one who's insistent on having three par-5's to get par up to 70, because to have variety you think you need to have par-5's. I would be more inclined to take your alternative suggestion at the end, but sometimes you have to do that for other holes, instead, and if you're going to wind up with eighteen you have to pick the least bothersome spot to make one of them the par-5, even if it's not as good a hole as some of the others.
In this particular case, our options for changing the routing are reduced because both the client and I think it's important to have two nine-hole choices. We believe that the nature of the resort, the terrain, and the summer weather means that a fair number of guests might choose to play nine holes per day instead of all 18 at once.
