Typicaly you dont have to use the clutch to go from lo to hi. You keep your foot on the accelerator, flip it to high, then let off the gas and it will pop into high as the load is taken off the rear end and the engine speed goes down. Takes some practice as you'll tend to feel it slam into gear till you figgure out your shift points and throttle positions.
I'm still not up on that myself so much tho, I still like to switch it, let up on the gas and push the clutch in momentarily as the engine winds down and then release the clutch and roll onto the gas again. Shifting up gets pretty easy with some practice, down shifting is a whole other matter tho, I'm still learning that one!

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion! :P
