Instead of a spring, could you put some kind of viscous damper* on it? Like those things they put on screen doors to keep them from flying out of your hand in a high wind? Yes it would slow down your "up" speed a little, but it would slow down your "down" speed a lot.


*caveat: check the rules to make sure it's legal.
