at the suggestion of richard hudgins i purchased and use the smartcamber setup, like it real well. set the camber to within a 1/10th and same for the caster. the hands free deal might be beneficial but you can use bungee cords to tie it to the wheel. i'll never use a bubble again.

shop around and you should be able to get a decent deal.
