Oh, I would LOVE to have the definitive answer to this question! I haven't tried Apex Dance but I would like to as I suspect they may be better for spinning than MK Dance and they can't be all bad if Guillaume Cizeron skates on them. What I can tell you, however, is that MK Dance are a totally different ballgame from Coronation Dance. They are slick and smooth and just the fastest blades out there. I think there is a big difference in the quality of the steel used for the different level blades. Whilst Coronation Ace are great intermediate blades and I think that the Dance version are a good step to get beginner dancers adjusted to the shortened heel, anybody who has skated on high level blades is going to find them sluggish, like going from a sports car to an old, underpowered jalopy. If you can't afford to try both, pick MK Dance because they will NOT disappoint.
