All round value for money
, I'd recommend Dacron for your new headsail, especially if it is going to be used while you are improving your skills. Dacron will last the longest of just about all the available materials. It is also relatively cheap
. Its weakness is that is stretches more than most of the other options... but in light airs that shouldn't be a problem. To find a manufacturer, to me, its all about the individual loft / sailmaker
rather than a particular brand (Quantum / Doyle / UK-Halsey etc)... I'd take a wander around you local marina(s) and see what local loft's labels are on the sails
on boats of your size / age and then go to that loft for a quote.
