Joanna,
That is a good setup you explained. I will probably change to the hook on the sail but just tie the spectra to the eye on the mast. Might need a slight tug to get the sail down to the downhaul when setting up but I think even I didn't I would have enough play on the downhaul.
BTW... we talked about this in a previous thread- I looked up the base of my mast when I took it off the boat (hanging from my garage now) and I don't think the internal part of the downhaul is 6:1... I think it is 4:1 then doubles with the block on the sail. Seems this si fine with the Glaser main but needs more maybe with the Ullman.
