CDI Is Best Bet
I have CDI furler on my H26 and while not fancy, it has worked well. CDI can be purchased from discount catalogs - mine came from Defender Industries - check their web site. Sailrite who sells sail making kits, also sells CDI kits, and they provide a new video which helps you with installation. As with any furler, the jib will have to be modified and UV cover added. Good luck.
