Good point, donofland, about the sail having to be constructed of a heavier cloth in order to survive the higher winds when reefed. I doubt that this is a big of a deal as one might imagine. A mainsail, for example, is one weight of cloth for all wind ranges and nobody maligns the cloth weight issue here. L&L Pardey are sticklers for performance and don't even have an engine and they must have been at peace with the idea as they have a reefing/zipper genoa.
I might be wrong here but I believe cloth weight is mostly related to the size of the boat and sails and less about wind range. A boat with a 20ft mast has shorter unsupported sections of sailcloth than a boat with a 40ft mast. Also the boat with the 20ft mast has a 100sqft sail where as the boat with a 40ft mast has 400sqft of sail and with the wind force being a cube of the velocity.... well you get the picture.
For any given wind speed the 40ft mast boat must have cloth to support much heavier loads of it's 400sqft sail than the 100sqft sail of the 20ft mast boat in the same wind. If heavier cloth made for poor performance in any appreciable way then the little boats would be sailing circles around the big ones in races.
If you decide to go ahead and get a slab-reef in your genoa, don't just let the sailmaker put a horizontal set of reef points at %30 of the sail area. Have him angle the reef in such a way as the new reefed clew, when set, will have a similar but slightly more horizontal angle of the sheet with the SAME CAR POSITION. This will allow you to reef without also having to change your genoa car positions and will simplify the reefing operation significantly. Also the slightly more horizontal pull, in favor of an identical sheet angle to the unreefed state, is better for higher winds.
I have a sauna on my boat, therefore I win.
