I played on the quaboings at the Vibram this year. They're pretty cool, but concrete is better of course! :-) Better than fly pads, not not nearly as portable / removable. You just roll up flypads. To make teepads with quaboings, you have to glue several 2' x 2' squares together. The glue is permanent, and if you need to move the teepads, you'd have some big, heavy monolithic slabs to deal with.
