Jay,

You really don't want to bulk the over over the outside. It will jam up entering the clutch. You need to insert line into the middle of the halyard to "bulk" it up. Try pulling 3/16" amsteel/dyneema into the core.

Also for the clutch to work best, bulk up to the max line diameter for the clutch rating. At the bottom end of the range, the rope will almost always slip.
