which knee is more sore I would guess the left??? Wolf or others may be able to notice more but what is the angle of your binding on your front foot. Hard to tell but it looked very shallow or nearly perpendicular to the board maybe 9 degrees???
If that is the case would it be better to open up that front binding angle to help take some pressure off the front knee.
If it's not the front knee then I'm way off and ignore my poor observation.
Hope your enjoying, looks like a nice hill that's for sure. Keep at it!!!
