My point is that if you are leaving the sail hanked on.... you don't need any help from the downhaul line.... I know I tried it that way and it gave no advantage .. there could be more opportunity for jamming... plus it took more time to rig it... again for no advantage, because the downhaul line is only attached to the top hank... and not any other part of the sail. Even if you disconnect the halyard, the downhaul line and the top hank provide the sail's security, not anything in between. You might try it without the weave next time out to see what I mean.
As far as using a pendant.... there is a very excellent article in a book I have where the author describes keeping each of his sails' hanks connected to a short pendant. When he brings a new sail on deck for a change the pendants keep the hanks organized in order when bringing down the old sail and attaching the new..... It's a neat way of keeping things organized at night or in busy seas..... I'll try to find the article ... If you like the security of hanked on sails, which many cruising sailors prefer... you'll want to see this system.
