Was looking at the Selden products, a GX top down furler and removable bowsprit. I have a 5 -7 year old gennaker (no wire luff) bought from Cruising Direct (North). Just wondering if anyone has used one of these older gennakers with the GX. The internet rep from North said the sail weren't necessarily made for the top down furlers and it may not work but he didn't know for sure. Thanks.
