I checked my launch technique in my Big Sur video where I launch twice. Seems like I am launching half correct and half lazy. I keep contact with the grapevine with my left arm but let my right arm go to the coke bottle grip too early. I do the exact same thing on my second take off.
I think a very good thing is to go back to the training hill, probably at the beginning of every season to go through the basics of launching and landing.
The first launch starts at 1:04. Notice that Tony almost immediately rotates his hands.
