BTW, That Gale Sail thing in the ad looks way too big for a storm jib. I've never liked the idea of a storm jib located so far forward and high off the deck... same as the genoa. Much prefer an inner forestay with a hank on storm jib, no more than 60%, where it can be set lower and back (closer to center of effort) aligning better with the third mainsail reef. But you already have this sail and I think if you just want to try it out for those 25+ kt days, and not going offshore... then having a sleeve made to warp around the furled headsail, to be closed with the existing hanks of the sail could probably work decently.
