I have a D100 with traditional 3 1/8" "steam" ASI and ALT mounted either side of it for redundancy. When I fly I always use the steam gauges for speed and altitude and not the vertical ribbons on the
EFIS. As I make my turn on to final I'm always glancing at the ASI and not the EFIS. Similarly when I level from a climb I focus on the ALT and not the EFIS. I do use the EFIS VSI numbers though...
