We've gotten a little off-topic talking about double-clutching.

The revs will pretty much take care of themselves on a clutchless upshift. Just takes patience and a gentle touch.

Where you've got to conciously "match revs" is on a clutchless downshift. You have to blip the throttle to get the revs up PAST where they need to be for the gear you're downshifting to, and then drop into the gear just as you would on an upshift.

Thanks for the clarification. :)

Damn, I tried to clutchless shift today in the beater Tercel that I bought for my son. As beautifully as that car shifts with the clutch, it really DOES NOT like to clutchless shift. Even on upshifts, it won't do it without a really healthy neutral-rev first. Gonna have to practice that one some more so that I can talk my son through it. I think it's a skill that he needs to learn. (never know when the clutch hydraulics are gonna fail on your beater car!)
