Glad that Jeff B weighed in on the Bill Yates philosophy — "...a first hole being a par-3 of moderate length actually meters play quite nicely because all groups, in essence, play this hole in about the same time..." Bill and I used to discussed this regularly, with my take being that clients simply cannot get their hears around it, as Tom D aptly points out. It is the same with our decades of hearing from clients that they wanted (demanded) only "18-holes...7,000 yards...par-72...four threes...four fives...ten fours..."
I have a transformation project on the front burner currently. It is an 18-hole regulation that has been abandoned for three years. The "new" concept is to create a precision-length 18-hole course. To get it all to work, the opening hole will be a par-3. At first we got pushback. Thankfully, I had Bill Yates in mind and went though some "science" to get my clients to understand the benefits.
I can also attest that at Mountain Shadows (18-holes, all par-3), we have seen very little in the way of pace issues. The course simply handles the load — and again, it centers on the fact that we have holes that are all "equalizers" — nearly all groups complete the holes within accepted "time pars" and, unlike long fours and fives, the par-3s do not have multiple groups waiting to hit up, etc.
