I like the look of the 4'8 wing board but have been warned
against a double concave bottom shape. Apparently they stick and
cause a breaking effect on touchdown. Anyone got any experience
with this type of thing?

Somebody know wich are the differences between the 2019 Duotone
Wing and the new 2020 Echo?
Thanks in advance!

From what I can see from pics and the vidoes:
1) They have a "trim" line that keeps the Profile stable now and
allows some tuning. This is much better the floating profile
they had on the first wing.
2) They changed the Outline and reduced the anheadral. This
should give it more power and make it more stable.
3) Looks like they stiffened up the Boom Connection point.
I have not tried them yet, so this is just guessing from what I
can see.

As the guy who actually came up with that double concave keel
shape for SUP Foil boards I can tell you the following: I
decided to put that keel in there to keep the short Indiana
ProFoil supboards paddling straight. They however made the
Boards stick when trying to paddle/pump up onto the foil. For
winging you actually only notice that stickiness in really light
wind where you are using the pumping more than the wing to get
up and flying.
Regarding the Fanatic board. It will absorb the impact from
touching down, but it will stick a little and it will also start
tracking in the direction it touched down.

So simple flat bottom ( no concaves) best for high speed
touchdowns ( eg in big swell DW ) and for early release in
lighter winds ?

Thanks Gunnar...I actually have the Duotone 2019 4.0 wing and
I'm wondering if it's worth to buy the new one or to keep it one
season more...

I am pretty sure that you should upgrade. It looks like they
addressed most of the issues that the 2019 Wings had, and so it
should be a lot easier to ride with.

Directional stability makes a lot of sense, but I'm not
convinced that the payoff is worth it. The hardest thing for me
about SUP foiling (especially downwinding) is the pop-up. Surely
the more help you can get from your board shape here the better.
Bear in mind I'm relatively new to all this and am NOT a board
designer, so I'm happy to be proven wrong ;)
This is a link to a video sent me by Jimmy Lewis that shows how
a deep double concave hull causes a board to slow down so
dramatically on touchdown that it throws the rider 'over the
handlebars' so to speak. I've attached a picture below that
shows the board's hull shape
