You like clutchless shifting, and you're good at it. I don't mind using the clutch, and of all the manuals I've owned I've never had to replace a clutch. Looks like we're each happy with our own driving.
My brother's best friend (neighbor 3 doors down) since he was a little kid ended up with a volkswagon beetle (in 1979). The guy is mildly retarded, which makes for great "best friend" material. Nicest guy in the world, but dumb enough to annoy constantly unless you partition out that area of your brain while talking to him.
Grind it until you find it was his standard method of shifting.
I haven't ground a gear *not* using the clutch either... it I miss a shift, it doesn't sound like you think. It sound just like when you miss a gear. There is metal to metal contact when you miss a gear as well.
Especially with these modern manual transmissions.
