The Mirage also has an 8' rocker, and if it is a typical Ultima blade, the less curved spin rocker leaves less available distance between the ball of the foot and where the toe touches down than most MK and Wilson Blades, so maybe it would be easier to turn almost any MK and Wilson blade. In particular, the Ultima blades I have tried are easy to scrape while turning or spinning, if you don't have perfect control.
(Yet some skaters disagree...)
By coincidence, history, bribery, or coach's preference (a few coaches dominate the high end field), MK Dance is used by most of the current highest end dancers.
One might well find one could get used to Dance blades. They aren't ideal for spins and jumps, and you may need to shift your weight a bit, but if you are ice dancing... Mean evil coaches with force us to make us keep our blades close to each other, and force us to go fast. Short tails and slim lines seem to help.
I will probably buy Reidell Eclipse Dance blades next, because of price. I placed them next to each other, and they looked similar. My MK slimline section was about 1/64" thinner than that of the measured Eclipse Dance sample, but my expert said that was within machining tolerance. Is it wrong to buy a clone?
