No arguments on any of those points.
The clunking surprised me the first time it happened. I read up on it and everything I found said normal, don't worry about it, not hurting anything, but remember the title on this thread is "wish list." I wish it was a little less jarring and a little quieter, but the clunking doesn't make me a QL hater by any measure.
I could be going a little slower, but when I'm running back mountain roads, I like to be in OR-1 so I feel like I'll clear without dragging the occasional pretty impressive water bar put in for the winter. I like to then cruise easy on the relatively smooth road between them without cycling back to normal height. It's those stretched I get the clunks from time to time. Or it's nice to be at OR-1 so I can get to OR-2 faster than from normal ride height when the obstacle needs a slow crawl over. Really nasty water bars, small trees, fallen rock, maybe a water crossing.
I think it's a good system overall. Mine's been problem free.
