I've only skimmed the first few posts because I have been driving a MT for a few years and don't think I need to learn at this point, but why would you need to push in the clutch twice to revmatch a downshift? That just seems like it would take waaaaay to long to do smoothly.

Just put the clutch in, select the lower gear, and as you are letting the clutch back out blip the throttle right before the engagement point. I guess I don't see the point of double clutching then.
