Hi Jonno,
let us know when registrations are opening for the Rottnest island race? Kim (my girlfrined) and I will try to make it then :0)
also, if you are looking for lighter (full carbon) custom made fins for your board, at reasonable prices, you could send an inquiry to french shaper Jerome Courtois:
[email protected]He made my board and my girlfriends' board + fins
you can check out his blog:
http://jc-kiteboards.fr/news/he makes a lot of nice & cool toys: foil boards, foldable surboards, race boards, etc
it was great meeting you and hopefully see you soon on the water :0)
