Sick of googling and not having much success, I'm looking for a larger us box fin to use in my 90ltr carve, something around 28cm.
Will be used with 5.4 and 6.4 NP Excess sails in bump and jump conditions around the 18-25 knot wind range, my weight is 95 kgs.
Can anyone suggest something that may suit ? Would ultimately like to get hold of several s/hand options otherwise one new one.

I've got a 28cm black project FSW used twice gathering dust in my shed - I don't have a us box board - flick us an email if ya keen - it's a great fin
