I would like to buy a Dual 175 but I am not sure if this is the right choice for me. Can you help?
I am looking for an all-round board that carves well on the piste, floats on powder and is maneuverable on bumpy terrain.
My weight is 76 kg and I am 187 cm tall. Soft boots are Salomon F2.0 fusion, mondo 29.5, external length 32 cm. For my height and size of feet I believe the 175 is the right choice for me, but looking at my weight shouldn't the 168 be better suited?

I am concerned that the Dual 175 might feel a bit like a big oil tanker when dealing with varied terrain (moguls, off-piste between trees and rocks...). On the other hand, the 168 is quite narrow and requires high binding angles to minimize boot overhang. That is no problem on a groomed piste, but on a bumpy piste or off-piste I prefer my binding angles low.
I know that a stiffer board carves less well on ice, but that’s a compromise I’m prepared to make.
Many thanks in advance,

G.
