I
routinely shift 1-3-5 in the MPGiata. It's geared super-sporty-low, even wth the oversize rear tires I put on to get the RPM down a bit.
Sometimes I am seduced into the 1-2-3-4-5 routine, simply because it truly is a fun shifter to use. So I play race-car driver once in a while.
Then I reach 50 km/h / 30 mph and calm down.
I haven't driven the Mirage enough to figure out if skip-shifting will be par for the course, though I have done it more than a couple of times.
