Hey Fellas
One thing I really really really liked about the Dotans was you didn't have to slow down or veer into the wind to apply them.
You were always looking forward and it only took 1 second to either raise them or lower them, when your in a crowd or running into the beach, there was never any panic cause you knew it took 1 second to change them. (maybe 1.5 sec's)
