Myself & a couple of mates got custom Stonkers from Alex about 18 months ago - great boards & great artwork! Alex offered up his prototype carbon earlier this year, and although it surfed really well - I don't think I'd get one (full carbon board that is). Being so light, but big - a bit of wind & it takes off upwards when you come off it, and it can't be good for old knees as there's no flex...finally, the one I demo'd was clear on carbon so no good in the sun.
2 of the 3 - 9'8" boards on their maiden voyage last year.
