DC300
There's a local public club that I enjoy playing from time to time... was a member there for years, played this course 1000+ times. There's a par3 there that plays downhill, in the 170-180 yard range, hazard in the front, bunker in the back, a tough bunker at that... green is a figure-8 design, wide but shallow, long usually leaving a short, delicate sand shot to a tight pin, and that front-green hazard staring you dead in the face from the opposite side. Not really an easy bunker shot.
So many times I would be asked, "what's the smart club here?" when playing with friends who weren't familiar with the hole. I'd always say something along the lines of, "well... for me, it plays about a 1/2 club less, on a calm day." They would be like, "okay, should I hit the 5-iron or 6-iron?"
There is no right answer there. He could hit 5-iron, he could hit 6-iron. Either club, if solidly struck, would probably work out just fine.
My answer to them in that situation (at least on a relatively calm day) was most always, "take the club you're most confident that you can hit solidly."
My overall opinion is that even if you happen to choose the wrong club, you're probably going to have a much more acceptable result swinging a club you have confidence in versus the club you'd rather not swing.
An overwhelming majority of the time - that advice holds true. Not all the time, but most of the time.
