I agree. I think most great designs ought to have one great par 3 of 150 or less yards.
Now, "straight forward", I don't know what you may be getting at Jason. Do you mean tough birdie, easy par? Or, perhaps, you don't feel it ought to have trickery, complexity, deception.
I do think that the hole should be very complex if it is an 8I to wedge. There has to be dire consequences for missing that so called "straight forward" and shortish shot, IMHO. The shorter the hole, the more contour and 3 putt potential ought to exist, I think. Or, big trouble for the missed green. 17 SandHills (150) with killer bunkers, 11 Wild Horse (125) with bunkers and big time contour and large green with distinct sections come to mind. 2 Sutton Bay (148?) was pretty interesting too, as both a drop shot and with the consequences of the missed shot.
