I'm with Dr Gray, there is nothing better than a long par 3/short par 4. I'm very surprised that Tom thinks most golfers don't like the long par 3. The response on here suggests otherwise but then this treehouse might not be wholly representative of golfers at large.
What this thread does do though is allow me to repeat my story about the 16th Carnoustie. Legend has it when Gary Player played it in one of the early Opens he stood up on the tee and gave it everything he had and still came up short. Two local worthies were watching this and as he stomped off the tee one of them asked him what club he had hit, to which he gruffly replied "driver". At that point the local worthy turned to his mate and said "see, I told you he under-clubbed".

I was under the impression that Tom Doak and many here don't have much respect for the concept of par. As I age and certain holes are less accessible "in regulation", I am moving toward that POV.
Hopefully, Niall, you had arrived at the conclusion (on the treehouse and reality) much earlier. I don't know that most golfers like a par 3 they can't reach with their best shot, but I think that variety is likely what most of us want. How hard is it to set up a golf course with 3 or 4 different challenges on the par 3s? Apparently it is because I typically have no more than a two club difference on four shots to the 3s, most often shorter irons.
As to long 3s, #5 at OSU's Scarlet course played around 235 yards from the back when 250y was a good drive. It was a hole that fell just right in the routing, sandwiched between a reachable in two par 5 and one that required two long shots to get to wedge distance. Whenever I left #5 with a 3, I was ready to tackle #6. At the NCAA's final in the mid-70s, most players hit fairway woods to #5 on the mild last day. Craig Stadler hit a towering long iron right at the hole that fell a few yards short of the green. He proceeded to slam the head of the club on the tee marker snapping it off (don't remember if he got up and down).
The new East (Hanse) Course at the PGA Headquarters facilities in Frisco has a 280+ yard par 3 to an elevated green guarded on the left with the sloping ground by a large nest of nasty bunkers. It is routed into the prevailing wind and the safe play to the right leaves a pitch to a green that runs away. There will be some long clubs hit on this hole by the pros, drivers on occasion even.
