K4 have made a good name for themselves in the Windsurfing World by offering a reasonably priced fin system for boards. Althought the fins are basically plastic (which in previous years were shunned..) they do work very well in multiple finned boards, as their flex gives the boards increased grip and control in the turns! The Ezzy fins are believed to offer even more speed due to the Assy design and the three variations of toe-in available (bit like setting up the steering of a car) aid the tracking of the board.. I think.
K4 say..

Our new ‘Leon’ rear quad Leon Jamaer signature fins are now available! The fastest and loosest fins in the range. Available in both the regular ‘dynamic flex’ material and for the first time our new ‘Super stiff’ material. Ride like Leon!
Some words from the man himself..
“We designed a fin that is very versatile so I can use it around the world from Hookipa to onshore conditions at home. Most of the time I use 14cm and in my bigger boards above 90 liters I like to use 15cm. In general I would choose the soft material when I want more control in powerful or choppy waves. They guarantee a really comfortable wavering sensation. If I want a bit more speed and aggression in smaller or more onshore conditions I rather take the stiff material. In my JP Quads I put the fins to the middle of the slot box. If the waves are small and I need a super tight bottom turn I put them roughly 5mm forward or, when waves get above logo high, I put them 5mm back from mid position. ”

We recommend going slightly bigger than usual with your front fins to give extra grip on the rail. As a guide.. Leon uses 10cm Ezzy fronts with his 14cm rears.
