I shouldn't be chiming in on a low-handicapper question but I've got to share one story. There's a bunch of guys I get together with once a year for a weekend. One round on Saturday we play an 18-hole stroke play competition and give a trophy for low net score and another for low gross score. I've only one time come close to winning the net trophy out of maybe 10 or so tries.
That year we were playing on a course a little too long and tough for me. So I resolved to play with a couple of absolute rules. The first rule was off the tee. If I could hit a driver and get within 150 yards of the green on a Par 4 I would. Otherwise, I'd tee off with a 4-iron then lay up with a 6-iron on my second shot. Second rule, if I could not hit the green with a 6-iron I would lay up to a good wedge distance (no trying to reach the green with fairway woods).
And most important rule, no matter where I was hitting my shot to the green I would aim at the exact geometric center of the green. Every time, even with a wedge, whether it was with my second shot or my fourth shot or whatever. In other words, just like there was no flag there.
The first outcome was, I shot one stroke under my handicap. My best score ever on that course or in that event by a long, long shot. Came in second, a guy shot net 2-under and beat me. The second outcome was that I was completely exhausted at the end of the round. I was actually in a bad mood after the round, not because I didn't win but because aiming at the middle of the green all day long was the hardest thing I've ever done on a golf course. In fact I've never tried it again. I know it's nuts but doing that all day feels like having every hair plucked out of your head, one by one by one. By the last hole, which had the flag tucked way over against an edge of the green with a five-foot dropoff into deep rough, I would have paid a hundred bucks for someone to tell me it was OK to hit my wedge third shot (after a layup) right toward that flag.
So I don't know the point of my story other than playing without flag might help my score but it would drain every stinkin' drop of fun from the game. Not worth it. It turns a game into something more like work.
