I weigh 74Kg (wet) and own Kode 74 and 86. Bigger I have Futura 101 , Isonic 101 et Futura 122 (pretty good customer of SB)-
I never hesitate betw the 74 and 86. The smallest is really for wave and turns/big jumps. The 86 is a small free wave, pretty fast on flat water with decent freeride fin.
I use Blade 4 and 4.7 for the 74l and Duke5.4 and Gator 6 for the 86L, no overlap.
A top board, highly recommended. Lovely in Wood)- Not sure Wood Carbon worth the extra $, for sure not on the second-hand market.
