What will be the most efficient ( fastest) way to go over high chop or even rumps ?

a) bend knees at the top of the chop to amortize vertical movement . this way the board ( and fin) remains with contact to the water for maximum time

b) straighten knees and allow board to bounce and fly from one bump to another . Quite hard on knees and possibly for the board too.

So what will be the best way to prepare for crossing bigger bumps at speed? Amortize or fly over?
If that helps I am talking about slalom gear and speeds > 25 ktn

To visualize situation we could imagine that we have to pass the wave left behind big motor boat without loosing too much speed.
Go hard or soft ? Stiffen position and fly over or amortize the impact bending legs then straighten soon after?
