This isn’t rocket science. You doing a turn on the wave you describe versus doing it on chest high mush. It’s the force of the wave that makes the difference, not your manly man legs, though I’m sure they’re lovely.I’m finding this quite entertaining that you can’t seem to wrap your mind around putting 100 lbs of force on a fin during a turn.
Let’s just consider mass. I’m 215 lbs.
Doing a bottom turn on a hollow over head wave when I’m leaned over with my back hand skimming the surface. About 75% of my weight is applied to the back foot that is directly over the fin cluster.
How is that NOT 100 lbs. of force on the fins?
or a hard top turn…
