Future replacement of the crossfader U-Mix Control.

I am using Cross right now with my external mixer but I am shopping to get a new mixer. I am now looking to keep it in the family and get the U-Mix Control Pro for my mixer. My main issue is the crossfader. What is the life of the fader and how easy is it to change out. I like to scratch and will wear a fader out. I love my innofader and will have a hard time giving it up and also can I put the innofader into the U-Mix Control? Any advise would be greatly appreciated.
