Does anyone know where to source carbon tube for battens? This is for a North formula sail, I believe the tube is 12mm diameter with a 2mm wall. I need it in lengths of about 1.6 metres. Broke the original battens in a piddling little shore break :(

The North importer seems to be uninterested, I've tried several sailmakers who will talk happily about their sails but seem to have taken a vow of silence when it comes to materials, and the one carbon foundry I tracked down only supplies tube in 1m lengths. There's a guy in Switzerland who is happy to ship it to me at great expense, but is nice enough to express puzzlement that I'd need to be sourcing the stuff from Switzerland.

Any pointers greatly appreciated.
