You need more rake I think because the tail rocker, or use this fins when the wave has power. I have the chuby at 5.10 and the first fins i tried was K.2.1 pc , not liked it, the board was slowly. I bought the scarfini fins manta and the board goes like a knife in the wave. The center fin is small than the side and the foil is similar to futures vetctor. Sorry for my english
Yo, im 5'8 and about 68-70kg so 150-155 i love my 5'9 in 2ft+ its suprising how well it goes in pretty solid surf too and 1-2ft can be fine with a bit of push and shape... its a great board and came alive when i put in some rob machado future fins. i wasnt expecting them to make much difference but those little bamboo bangers rock
iv heard good things about the dusty payne fins from kinetic, i looked at some before i got my machados, reckon theyd go pretty good but they have a flat inside foil and i like the feel of the concave inside foiled futures... worth a look tho
I stuck Kinetic Jack Freestones on this board after not much joy with Kinetic Parkos / Scarfini mantas ...totally changed my opinion about this board...Mostly walled up knee to head waves. I'm 170lbs on a 5'11.
First wanted to say that the Chedda is a beautifully designed board by Luke Short with great lines and awesome rails. I love how the additional foam is 'magically' placed in upper core of the board without it feeling bulky...just awesome!!
One thing that I've experienced with this board is that it is extremely sensitive to fin choices even with the same fin template! 'Asymmetric' sets (smaller back fin) have been more unstable as compared to 'symmetric' sets (same back and rear fins) like all F4 as with some other boards. Foiled fins even those matched for my weight (~60kg) have also not worked as consistently as I would have hoped. My best combination as of lately has been flat foiled medium-stiff raked fins with a small surface area (Future AM3 for me).
The waves I use this board in are medium grovelly to clean face reef breaks up to head high.
Fin combinations I have used:
F4v2 composite (area: 14.22") /F3 or F2 (12.56") back - Very unstable
F4 composite (area: 14.22")/F4 back - Stable and looser in release than foils but less drive
F4v2 composite (area: 14.22") /F4 back - Very stable and responsive but works best when waves are steeper and have more power. This hangs or sticks more than blackstick so easier to catch the rail.
F4v2 blackstick (area: 14.22")/F4 back - Very stable and responsive but works best when waves are steeper and have more power.
F4v2 honeycomb (area: 14.22")/F4 back - Extremely stiff and very disappointing on this board even in stronger surf
AM1v2 (side - area: 14.84"/ back - area: 13.35") blackstick - Looser than F4v2 blackstick but not as stable.
EAv2 composite (area: 15.16")- Very sticky. Extreme vector foil on this one. Also, I think it was too much area for my weight.
WCT techflex (area: 14.89") - Didn't respond well. Too much fin and stiffness for my weight.
AM3 honeycomb (area: 13.80") - Loose and most responsive of all combinations yet holds decently with size. Head high with very slight sliding. Have proven to be very versatile in weak and good surf. Works well with fat wall type or steep face waves.
Persevere looking for the right fins. I know that it can be frustrating to have a session go to waste because of fins that aren't matched to your board but when it works out it's awesome. Check out the fin tree or maybe even borrow a set from your friends just to find out what works.
