We wanted to go to pin sheets, but the members complained about having to pick them up and carry them around.
We did decide to go away from red white blue, the colors just looked out of place on a golf course. We've gone to green (front), white and gold (back). The nice thing is that the gold stands out nicely for back pin positions, where it's sometimes hard to see the flag against a background of trees. On some greens that aren't deep, we just have a white flag all the time. On the greens that are very deep, I think the color coding helps provide information that may speed play...but the majority of golfers are not using some form of gps device and getting the exact yardage, so I'm not sure that it's even relevant anymore for most people.
