One GOOD thing when you get older you get more stubborn ,so get out there and give it another crack
we all still have **** days .I'm with others, old sails seem a bit twitchy and overpower more easy .
A camless slalom sail would be a good move ,but keep at it ,wash that wetsuit in some shampoo and conditioner in a hot shower
that will soften it up ..surely you haven't put on weight

if you can see ya toes your good but if you can't see the other thing
your in the **** .
