I'm looking to convert my x7.0 ice skates. Couple of questions, has anyone used the Reebok labels chassis? It's the only one I can  get in the UK by the looks of things, so is it any good?  Alternatively I have a hummer chassis but am not sure about changing the outsole to fit the wheels.  Ideal I would like an aluminium hi lo mission chassis, but I can't get them either in the UK.
