I dislike the 06 instruments so much, that I guesstimated speed on my 06 test ride by referencing the tach, instead of the speedo. BTW, thanks to Beal for letting me test ride.
As far as being optically challenged is concerned... The optometrist told me at age-30 "You shouldn't be having these kind of problems until at least 50". I wear a monovision setup and don't have much problem with focus on the instruments. It's the level of information that has to be deciphered in a given moment that bothers me. Too much to look at, too much guess work for a fraction of a second.
I think the tick marks are a great idea. Every millisecond that I can divert from reading instruments to piloting skills, allows me to twist a bit harder.
Hell, I might just engineer a sweep display LCD speedo that drops in place of the analog dial. Of course I'll have to put sliders on it so that I don't scratch it when I drop the damn thing!
