I like the Surf Band from Malibu/Axis for this functionality rather than the transom touch pad kind of situation. It looks like you have to swipe to indicate your side. I haven't had anyone complain about the driver running the surf side except when I forget to switch it back on after restarting due to the stupid software issue that makes the wake plate inoperable if the surf switch is on during the reboot cycle.

I really like that there are very few optional selections on the Supra line.

By the way, we really like our yellow/black boat. makes me feel like Batman!
