Sorry I threw the D2 in there, my error. Also I should have specified, Ventus 2b. As I am only 5' 9" in height the V2a would be ok but with a wide chest it would be tight, V2b more suitable.
I am leaning toward buying a V2b.
I am asking about the flight characteristics of a Discus as a comparator to that of the V2b outside of flap use. Does the V2b have a&& biting habits.
