They're fine, just like every other sail made in the past 24 years.
I have friends who need sails newer than 3 year old design.
I sail by them all the time with 1998 sails.
Robbie Naish in 1984 sails waay better than me using his 1984 gear.
And he sailed waaaay better than you.
Wow! You can judge a sail by sailing by it! Impressive!!!!! And you have very detail and subtle judgment: everything works! Interestingly you get very precise when it comes to dates. Nothing works before 1998, although if you are Robby Nash it does with a 1984 sail. Bravo!
