i voted independent rotating because all things being equal, its a better system and can't see the advantages of a solid axel

and when i say 'all things being equal' i do mean a very select number of things, excluding manufacuring costs, design, implimentation and all those carefully chosen other factors have been ignored!

I have not yet seen a real life example of a non-sloppy freely rotating example of the free rotating wheels, but I would like it!
