Clarification... Removing weight from the dowsing line helps when the wind goes really light. The chute will collapse less when the wind goes to nothing. You can remove the outer cover but are left with the problem here of finishing the cover to the core at a point where it must be pulled through suffers, blocks and cleats. It is easier to remove the core and leave just the cover. To do so just pick a spot around the front beam on the way to the hoisted chute... poke through the jacket and grab the core. Scrunch up the jacket along the line an work the core out. Cut off the excess core and stuff the core tail back into the cover. Like Chris said, don't try it on old line.
