    There's situations for both styles of shifting.

    When I take off on a steep hill, heavily loaded, I double clutch. I can grab the gears faster, and it makes splitting the bottom side of an 18-speed a whole lot easier in my book when you're heavy.

    Cruising out on the high plains, I'll float 'em all day long.

    And almost without fail, I'll stab the clutch (once) to pull the auxiliary out of gear when splitting both boxes on a set of sticks.

    It has something to do with the transmission not having synchronizers it ensures the pressure plate completely disengages it also lets the revs drop making upshifts smoother on the driveline. So better said it's easier on your equipment.

    I don't get paid enough to double clutch. I will keep floating.

    Take your truck out and intentionally blow a shift while double clutching... i guarantee you it wont smoothly pull into gear like a car.
    Correct RPM match is all that gets it into gear.

    Double clutching doesnt make for faster shifting, it takes as long as it takes...now you can slam it through but thats a different story.

    Yeah, that is more realistic. there is more leeway but not as much as i made it sound.

    You only have to double clutch while you're testing. After you get the license you can shift as you want. It might not make sense but just roll with it.

    i still double clutch when shifting up once to take the power off the driveline and once to ease in the next gear when downshifting i clutch to take it out of gear and then i feel it into the proper lower gear this method may be old school but it makes a smooth as glass transition on all your shifting and after almost a million miles i never tore up a clutch,tranny,u joint or rear end. proper double clutching is an art that was lost when they started televising nascar. happy trails
