Obviously, there's no "right" answer. As a golfer, I've played courses with extended flag sticks, and courses where the shot to the green was blind entirely or depending on where you drove the ball, but would not have been if a extended flag stick had been used. Off hand, I'd say that at a public or resort course extending the flag stick could speed up play. At a club course, that's normally less important. At my club we've had some greens that were so much higher than the fairway you couldn't see the flag stick from a typical drive, but could have if the stick was taller. So, what to do? One of us would run up ahead to get a bead on the flag and report back to all others, including opponents. I'm not certain about that from a rules standpoint, but for day-to-day play, that's what we did. Personally, if it was my call, I'd say to go with the normal sticks and see what happens. Maybe it's a good strategic ploy in your case, demanding a shot down the left if you want to see the stick. If the normal stick tunrs out to be a problem for most golfers, go buy a longer one. Again, just a personal view.
