I use 6th all the time on the highway. Makes the tank last longer. It only takes half a second to click down twice and go!
So far i have had my '97' for 1k miles, and on the highway cruising in 6th low rpm's, fine for sipping fuel, 38 mpg, however to get away from the asshole tailgater, drop 2 cogs and the bullet is ripping. At highway speed not too far over the limit, 70-80, the bird will "bog" a little in 6th, i am only taching 4.5k maybe, but like i said drop 2 cogs and hang on for the ride.
