I don't think there is any way to balance that field! I did hold rating to operate out of there, and Meribel 25 years ago. I didn't operate a jet in there, but at a guess any jet would need to commit at circa 50 kts, or maybe even less.
In anything that requires most of the runway to get airbourne out of Courchevel, the trick is NOT to rotate while still on the downward slope, even if you have the speed to do it. Rotating just prior to where the slope levels off is a sure way to guarantee a tail strike. The guy in the clip did it perfectly, and I'm pretty sure he knew the place well.
