Just to add: The Dynon 180 on my XS has the static and pitot connected in 
parallel
with analog backup instruments. I tried to use the stall warner input as AoA
input for the Dynon and can report that it doesn't work. The AA system in the
Dyson expects more pressure at higher angle of attacks, and of course the stall
warner tube produces a lower pressure at higher angle of attacks. I agree
with the opinion that the Dynon AoA tube is awfully big and heavy. Must look
great on a 747. There is a good chance the tube bending system will work. 
A second thought is that i am not really interested in AoA, because especially
in the Europa, the AoA varies greatly between flyable speeds between 50 and 150
knots. It's the stall that i am interested in, and that has little to do with
the Angle of Attack. But please correct me if this makes no sense!
