I recall reading that Thrust II (running at 1000mph but somewhat closer to the ground) used analog meters so that a glance could get an approximate value and rate of change quickly and in a situation of heavy pilot vibration. I couldn't find the original article, but I found this breathless page from the manufacturer which alludes to this.
