I don't like stay set or stay set x. Too many other choices that are easier to splice, strech and creep less. But they do cost more. I usually try out line on a different boat and decide if I want it on mine. Also, try pricing out some hightech line one size smaller. Usually the strength is plenty, and you'll save some money as well. Things like a mainsheet doesn't need to be 1/2" in dia. Try apex in 5/16". Great feel, strong, floats and doesn't absorb water. And b/c its strong and a blend, you don't need 1/2" for strength or feel/grip. You save money by downsizing to a higher tech thinner diameter.
Lots of options for your needs. No boat should have all the same type of line (that's just lazy). Also, you can make your own halyards using a cheap double braid that feels good and then tapering to a high tech single braid to save money as well. However, this requires research and a lot of measuring, splicing, stripping, tapering, whipping, etc.
My suggestion, call Annapolis performance sailing and talk to their line guy.
