J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Tuff-Luff Aero foil

Just out of curiousity, has anyone used or considered the Harken Carbo Foil option? I've used Tuff Luff foils for years. I know very little about the Harken product. If one is to believe their marketing, it sounds like a compelling alternative at a very similar price.

Thanks,
