Having had and used the single cue FD all my career, I don't think I could make a dual cue work for me if I were confronted with one.
It seemed so intuitive to marry up with the little yellow "v."
On the other hand, I was "raised" with the crossbar. Then switched over to an airplane with "v bars" and hated it!
The only way for me to fly it was either with A/P on, or raw data... Grew quite proficient in the latter thanks to the v-bar...
