Im going to have to disagree with RP, respectfully. You're right in one way, they don't make em like they used to, and that's proabably a good thing
but seriously the new sails are made with better materials and have a more uniform stretch than the old ones and will probably last longer too. They aren't cheap, but you get what you pay for. If your just out fun sailing every few weekends, older sails are probably the way to go, but if you're racing, nothing beats a new crisp set of sails to give you an edge! I do wish Hobie would mix up the colors a bit more, like the old school ones as they are great looking and very varied. Good luck!
