When dealing in a "formula" class, money usually rules as king! The "factory sails" will never be up to par with the other fast lofts competing for a chunk of the pie. What sail loft was the world's winner using? It wasn't factory!
This is a class that you must make a choice to sail in. Being split with the F18 and 'one-design' concept is tough. To be on the cutting edge, it requires 2 sets of sails because the F18 (boat and sails) will constantly evolve. In the USA, you have to make a choice, it will get expensive, and you just have to deal with it.
So, if you want to sail "Hobie", that's one complete set of sails. True cutting edge F18, another. This is the way it is. And this is true for other components of the boat as well. Your choice. It's an arms race (money) the little guy will have trouble competing in.
