First thing that comes to mind is that the is no material that has to flex that could wear out or whatever. They probably weigh more than a regular spring..... Actually I dunno. If there were raised areas in the playing field this year I wanted to bust up some of these rolley chairs in the classrooms where we work, and jack the little gas shock type deals to use as shocks for our bot. As it is I guess we get to focus more on a grabber thingy. Dangit Im off topic again.
