Did a little higher speed testing down one of our local washed out gravel roads.
It seems that it doesn't return to center as good as it once was, which made me realize I didn't do a final check on caster at ride height.
But I did test the flex, I'm very happy with my (only) 10" travel shocks.
This was light enough in the left rear that with a little push I could lift the tire off the ground.
The right rear just barely touches the back of the flare, but that bumpstop was more compressed than the front right shown.
