Manual transmissions have 5 (or 6) gears named sequencially for a reason. I use all 5 upshifting, but usually skip a gear downshift (revmatching) to save clutch life or for fast stopping. I knew an old guy in Poland that you never used second or fourth gear, and he dropped his transmission after 2 years of driving. Opel omega, those things have awesome trannies too. And if you know how to shift properly (proper timing and proper RPM) with no slipping between gears (like ever single person I know does) it does not wear the clutch much at all. I have driven 15k on my clutch so far, and when I had to take the tranny out it looked brand new, on .03 mm in material gone. And I drive fast and do plenty of peelouts.
