I agree; in smooth air it flies hands off really well. Unfortunately smooth air seems to be pretty rare for me. I guess it's when I'm getting knocked around and trying to fold a chart or eat a sandwich that I wish for more stability. Otherwise, if you have your hand on the stick when you get rocked, no big deal.
I do use my trim a lot though, so I am surprised to hear so many people say they hardly ever do. I think I would really miss it if it were gone. And while I can see the argument that less stability in roll is more fun, I can't say the same about pitch.

A slippery aircraft with very light controls indeed benefits from
positive stability. But that would not be a description of a Rebel. I
think I agree that my Rebel tends toward neutral stability compared to
some aircraft. Increased positive stability of my Rebel would make it
less fun and more work to fly though IMO. I find little need to add
stick corrections in smooth air and almost never touch the trim. I've
never seen any indication of negative stability in any axis and it is
remarkably speed stable on approaches. I'd guess that those of us with
the hoerner (sp.) type wing tips might have a bit more roll stability.
I've never done spiral dive testing as it accelerates too slowly to be a
concern for me. Any side slipping certainly picks up a wing as one
would want which does in fact demonstrate roll stability.
I've had Cessna and Grumman pilots tell me the Rebel is
more stable and requires less attention in cruise compared to their
machines. Some of that is probably perception from slightly more
friction in the controls but I like it just the way it is.

stability as Just on the positive side of neutral, and pitch, while
positive over a long period (I guess that would be dynamic) is close
to neutral short term (static?). I can fly hands off too, but I have
to hold the stick between my knees:) I have experimented with
initiating a turning descent and letting it loose...it didn't show
any signs of self correcting before my comfort level forced me to
take over. The good thing is it doesn't pick up speed going down
hill. Overall, I really like it, but every airplane is a compromise
of some sort.
