curious to hear some reports on anyone that has sailed the 76 & 84l as to the differance between the two. keen to pick up the 76l, am under 80kg so reckon the 84 would be bit too floaty.
they are both good boards. if your sailing scabs lots i'd go the 84 coz the extra volume there is really helpful. otherwise the 76 should be sweet.
a bit more info on where you sail and the conditions you likely to encounter. plus your rig sizes would help.
I have a 84 twin in my quiver as my high wind board.
I say high wind as I weigh in at 93 kg.
Are you after an all in 1 board or do you have other boards as part of your quiver ?
Where are you based and what beaches will you mainly be using it at ?
Can you get a test ride/demo on either or preferably both at the same time ?
Having just got back from xmas break where I took a single fin (light wind board) I got out on the twin fin last week and you couldn't wipe the smile from my dial.
IMO the twin fin simply allows you to get into places on the wave you couldn't or can't easily do on a single. Your wave count and enjoyment factor goes up exponentially
