I use a cleat, a very well adjusted one, I also have second block hanger on my boom, 65mm behind the first one, when I hook my mainsheet block onto that one the slight angle change takes the cleat out of the system, easier on the water then adjusting the cleat arm on the lower block. On a gusty day I use the back hanger.

Mainsheet is rarely in the cleat for more then a few seconds but they are handy.
