Ha! I used to shift my 51 Chevy pickemup truck without the clutch. Matching engine speed with were it should be in the gear you wanted was key. In essence matching the rpms is a manual way of synchronizing the gears.
Just today on the way to work I tried your clutchless upshifting. Amazing how smooth it is. I don't think I'll try clutchless downshifting Vera, but the clutchless upshifting I'll have to do to even dream of keeping up with your nad crushing machine! hehe
