I think this may have something to do with the pilot - perhaps - hmmmm
I have not ground anything in ages (with Classic boards and over-length warning pins) - pretty much since I changed the rears to Fournales (a bit over length iirc). And I am close to running off both tyres - So I don't intend to push further to find out - OK?
Good shorter travel hydraulics would not be choppy. Well, SHOULD not be. I have reduced my front travel and it's like velvet. Better than full travel. Knocked about 18-20mm off. No real nose diving even at rear rubber loses traction levels.
With hindsight (it's a wonderful thing) - I would liked to have had adjustable 2(3) stage damping. But it's one less thing for me to play with.
