Hello Stuart
A couple of years ago I fell in love with the set of sails Pat Morgan had on his 31(Phun) when he sailed around GB.
So last year I splashed out and replaced my well knackered genoa (Set like a pillowcase) for a Parker and Kay cruising laminates one. Wonderful sail and very good service but not cheap, although I did get discount for buying in mid year .
Speed was immediately up and pointing ability improved 10-20 degrees .
In hindsight I should have got a #3, easier to use short handed and not a lot slower, might even point higher still.
As for UV resistance etc, you should check with Parker and Kay , not a major problem in Wales at the moment.
