opinion:Its not the hit thats the problem, its chassis control, she tries to hook hard at the hit it seems.
Do you have travel limiters up front?
Shock control in front looks to be toast/nada.
In my minds eye the reason shock adjustment on rebound isn't making any difference is due really poor front suspension control and, perhaps too much bottle too soon but, wont know that until front end is tightened up.
If you just have90/10 front shocks- are they adjustable at all- can you go to 70/30 and at least lengthen up the bump stops?
I would tighten up rebound on rear shocks as far as they would go and try to tighten up the front.
Man i wish you could find a set of scales.

It also appears you "might" still need a little more air pressure.
We have found here that tires actually need a bit more pressure than we used to think.
