I was pulling in all the reef lines, and even went to Harken blocks for most of the friction points. What was pointed out to me was the wear and tear on the leach of the sail from all the pulling of the reef lines over it. So I just climb up and stow them after dropping the main. For intermediate reefs I snug up the unused ones to keep the loose lines from slapping around. It is interesting that on my L400 there's a placard against getting on the upper deck. What a joke!
