Quest
I replaced my 28.5 main sail last year with a Quest product. After alot of shopping around it seemed the best buy. Upon reciept of the sail I layed it out next to the original JSI on the floor of a local gym and the difference in construction and design were, to put it mildedly, not in the same leage. I found that it included as standard many features that others charge as options. It sails great in light to mid air, but is a bit over powered it wind greater than 15 knots (true). I specified the design to include full battens in the top two slots and a shelf foot, the performance increase was outstanding. I plan to replace my jib next year with a Quantum, Quest's parent product.
