Haven't flown either.
Do they have a yaw/roll couple PROBLEM as opposed to exhibiting a tendency?
Getting back to swept wings, the B757 could exhibit a slight tendency to a roll cycle on approach (about 1 cps) which we put down to PIO.
Edited to say: M(F)S please don't think I am challenging your aerodynamic knowledge. I was probably incorrect to state <<Straight wing aircraft do not suffer from dutch roll>> but I have never flown nor heard of a straight wing aircraft going into service which suffered from dutch roll to the extent of the early swept wing aircraft of the B707 era.
