Ive recently purchased the 5'8" carbon.
I am 65kg, using a Axis S set up with either the 102 or the 82 wing with a 440 tail.
So far it has been awesome. Have used it for wing foiling in very choppy water and has been easy to stand up on and get balance prior to take off.
The foot placement holes are in the correct spot for strap option also.
What I noticed most is the ability to get flying, the other boards Ive used have taken a fair bit of technique and pumping but the WC takes a quick push down on the nose then up it pops.
It seems the distribution of floatation is slightly further aft which makes it easier to stand when not flying and reduce the swing factor when the board is up.
Pumping is natural and not difficult.
Cant speak on the longevity of the board yet but seems solid enough at the moment.
Cons- Not sure about the 'all black' colour. It heats up very quickly when not in the water so I cant put it on my roof. (..there's something else about "all black" that makes me sweat...cant put my finger on it

)
-When paddling it tends to shimmy on the water, my board does not have the side fins.
Over all, in the week that I've had the board my foiling has improved dramatically, my turns are much easier and Catching the down with swell/chop is increasingly more fun.
Hope this helps.
