Ahh clutchless shifting.
I've done it, but I'm not perfect at it, and I don't have a manual car anymore, so I can't practice it. and even if I did I would not do it more than a few times if that.
But My dad is a pro at it. and can shift smoothly thourghout the gears.
We used to go racing around in a 68 vette he had, using the clutch only for first gear. Though that car did not have a hydraulic clutch either. But the hurst shifter on it was very solid and shifted clean.
