You migth want to look at the superspeed HOT sails maui sail. It has no cambers, but it looks just like a sail with cambers. They say, that it hast the good sides of both cam and nocam sails, so that would be that its easy to jibe and it has a lot of power. The downside of it is that you would have to buy a new mast because it works with an RDM. That might be an obstacle, BUT if you have the money to buy it its definately a good choice.
Here is a link to its site and to a video about the sail...
