I visited a club in Nashville that has a board like that. It was very functional. My concern was when multiple pilots are on the same frequency it was difficult to know the order in which you were to fly. I fly Channel 38. There were two other people on 38. With our system (freq pins), the next card in line is the person up and you just put your card in the rear. the pin is passed to the next person and it flows smoothly. With the other system (PVC), the guys past the pin back and forth and I felt I was a bother because I had to keep asking for the pin.
Other than that, I did like that system.

Our club utilizes two rows of numbered PVC pipes very effectively - even #'s on top, odd #'s below.
