Hey windwarrior
Jp told everyone himself on the video interviews on the boardseeker website. He was interviewed back in Guincho last year and had been on the (Kieth T)twin fin for quite a few months at that stage.
This sort of stuff has been going on for ever. When Jp was sponsored by F2 he had island unique shape his boards.
Most pros have a budget to have X number of boards made per year by anyone as long as they are painted right to look like the brand sponsor.
I can't wait for the brochure hype in 2009 telling us a board is shaped by "a" when it was clearly made by "B". Will they tell the truth or con everyone with marketing.
I don't think the JP brochure is going to say their new twinny was developed by Keith at Quatro.

Cheers
Paul
P.s. Does anyone else think Kauli's new board looks a bit more gunny that his usual wide nose tiny tail & short boards? could be new style.
