K4 fins ... I'm exited! partial review

Woo Hoo Thanks MR POSTMAN! I'm exited I've scored a couple of K4 twin fins!!!!! unfortunately I can't review them yet as I haven't tried them out, So there's probably not going to be any wind for ages now(sorry about that everyone)
I hear these fins have been selling like hot cakes in Euro land.
They have a nice looking plan shape which does look a bit chunky compared to what I'm used too, they feel pretty strong I've been twisting, bending and flexing them. One of the best bits is the weight I reckon they are about half the weight of my G10 fins! I really can't believe how light they feel. OK that's my review over...... until I get to try them out.

Oh Heres why I am exited ..... I really like fins that have flex, they enable me to do tighter top and bottom turns that just flow, don't break free suddenly and after they have broken free flexi fins grip back slow and evenly. But in G10 which I have been using to get a flexible fin they have to be foiled quite thin which means that they have a flatter foil which is cr4p for early planing especially sailing at places like Scarbs that has a rip it, as decreases your early planing heaps and flatter foils arn't good for heavier guys. But because these K4 fins have been moulded I believe they have been able to position different materials in the mould to give them flex, yet still have the thickness of a full foil which equals early planing, and still have the twist and recoil reflex of a thin thin G10 fin.



Here's the official blurb about these fins


Weight Saving Box - The fin box design is lighter than any other system on the market,
setting a new industry standard. Amazingly strong and super light weight.
Super Core Foil - The foil shapes of the K4 fins are a unique combination of sailing
knowledge and technical know how. The fins are based on a super core technology that
ensures ultimate performance whatever the conditions.
Opto-Glass Construction - Moulded resin with long fibreglass matrix. The Opto-Glass
construction creates the ultimate snappy, tight and lightweight fin retaining the proper flex
pattern for performance. Opto-Glass is a bench mark in the industry, the new revolution
and unique to K4.
Accura Flex Technology - K4 fins have been designed to have a unique flex property
that allows them to do what you want. Soft tip and stiff base allows you to load the fin up
producing killer turns. It#700;ll still ride like your G10 fins but it#700;ll bring the board alive on a
wave!
Load Point Relief - K4 fins have analysed the pressure zones to find specific load points.
Knowing where these are have allowed them to diffuse the pressure and accommodate a
better flex recoil characteristic.

Heres a pic of a 16cm and a 17cm, I'll put them in my board tomorrow and take more pics comparing their flex to the G10 flex. Come on wind

Hey Troppo what size did you get ?

ahh..... and the penny drops for me, now i understand a few more things.

great review, keen to read more.

could you guys let me know if the twin fins are 80/20 foiled?

cheers.

Ok finally(forgot where I stored them on my pc) got round to putting up these pics showing the flex of different fins. Still no wind to try them, maybe tomorrow.
I hope Ive got them all in the right order (the pics that is)
pic1 16 and a 17 K4 just in the boxes
pic2 16 and 17 k4 being evenly squeezed together to show the twist
pic3 meanline(my favourite fins) g10 17 (as used in mistral 09 twins) and k4 in box
pic4 meanline and k4 being evenly squeezed together to show the flex of both

NEARLY A MONTH LATER AND STILL NO WIND !!!!! YES I AM YELLING
