I think you need to cleat in light to about 15, and sail by the telltales and the feel of the boat. Above 15 I agree or if there are a lot of puffs, but then you should be watching the water and be ready for them. In the light stuff I think it is more important to watch the telltales and the feel of the boat and keep movement and healing to a minimum.

Just my 2 cents,
