I know the Fight is not out for another week, but what I really want to see is a comparison video made of the Fight and the Roto Disturbed. Yes I know the Disturbed is discontinued, but that ball has a similar diff and and slots very close to where the Fight slots. I am still getting plenty of mileage out of my Disturbed...but I know I will need something soon to replace it and Disturbeds are getting tough to find.
