Actually I do have one, and its never been sailed. I even kept it in its cover.
I won't sell it though, just so I can dream of one day using it.
What's so special about them at the moment?
They are apparently needed to break the 40 knot barrier. Sort of like the swept back wing was needed for planes to break the sound barrier.
I need a +40 knots in either a 2 Sec peak or 5x10 - not fussy but would prefer the 5x10 and willing to trade a 24.8 knot Alpha, a Drake fin and a 25knot SE wind
Ive got one on order... it will arrive when i get the golden ticket for my own private show from Jennifer Hawkins and Megan Gale jumping on a trampoline wearing bikinis.. 
Not holding my breath..
So that's a no then !!
Anyone have any suggestions I swear hamma had a raked back fin from Lockwood he didn't want after a bad day at sandy ... Should of had that one ! If so many people ant one why are they not making them ... I just want something fast in weedy conditions ..
Suggestions welcome
C3 Slingshot cheaper too. You could buy two for the price of a KA fin,
delivery time is less than a week. i use mine as a semi weed fin and it works fine
