I have 2 sails at the moment, a 6.0 and 4.5, i know i really should have a 5.2ish somewhere in there but I'm moving soon so don't feel like extending my 'quiver' of sails just yet.
I use the 6.0 up to a regular bft 5, anything above and I need the 4.5. During typhoons here (in Hong Kong) the 4.5 is good at which point the wind is 6-7, that's when I need a board that is ready to take a chop beating and stay under control despite the conditions.
I too think that a Kode, with a single back strap, would be good for these conditions.
