I did an unusual (for a Coupe owner) amount of high altitude cross country flying. When I fly, I often like to go places. And, I have a strong tendency toward motion sickness (mostly cured by learning to fly) that makes me prefer being above the thermal layer in the silky-smooth air. Cross country trips up there may be boring, but they don't make me want to heave. Also, from 10,000'-12,000', if you were to have any engine problems you would get to choose which airport you want to land on in "flyover" country. And, the fuel savings at 2400 rpm and below can be dramatic. Getting high and leaning the engine can increase your range so much (with controlled human liquid intake) that you can skip a fuel stop on a long cross country trip and save an hour to two hours time along with the money. Westerners, where there are high altitude airports and where the 7,000'-10,000' scenic things are rocks, not clouds, can benefit from having a working mixture control for climb. Also, the fuel stops tend to be farther apart west of Omaha. And for John Brier, as far as I've heard, Marvel Schebler carbs are about the same as Stromberg carbs except they react a bit faster to changes in the mixture control. Ed
