I moved from Coronation Ace to MK Dance. It was a huge change. But wow - The MK Dance were so much faster, probably because the working part of the blade is thinner. And I stopped tripping on the back of my blades when my teachers said that "neat feet" required the free foot to sometimes be placed as close to the back of the skating foot as possible. (Other aspects - thin blades change edges a bit more quickly, and for whatever reasons Dance blades are easier to twizzle on, harder to spin on.) I loved the MK Dance blades. And most of the really high end ice dancers use them, though it may be partly because the MK/Wilson manufacturer gives away blades to some of the best skaters. But, alas, MK Dance aren't cheap.
BTW, in theory thin blades are harder to balance. I didn't notice that on the MK Dance - but I have noticed it a lot on speed skates, which are even thinner. You may also notice that MK Dance are a little higher off the ice - maybe to give you room to edge more without scraping the sides of the boots as much, especially on the deeply edged underpushes that many ice dancers love. Again, the extra height might be a slight balance issue, but the balance issue will likely disappear with time.
For economic reasons I switched to Ultima Dance - which was an even bigger change, because Ultima shapes the front of blades a lot different than MK and Wilson - the spin rocker and toe pick position will be quite different from Wilson Coronation Ace, and I think from the MK Pro, they I never used the latter blade. Unless you are very adaptable, you might want to stay away from Ultima. I'm not sure, but I think Eclipse Dance might be roughly comparable to MK Dance, but are cheaper. Though none of the dance blades that I know of are particularly cheap. I do know that some of my ice dance teachers chose to dance on freestyle blades, so it is possible.
You can simulate higher heels by shimming the mounts, adding something like tape between the rear mounting plate and the heel, but that gets a little complicated, because you don't want to warp the blade, by forcing the plates to bend from having all the pressure at the back of each mount point - so you may need less tape width at the very back, and to also add a little tape to the front of the front plate mount. High heels or similarly shimmed mounts have some side effects, like moving the toe pick further from the ice, and possibly changing your comfortable balance points. BTW, I found high heels very painful, and had to have my dance boots modified to drop them, but I am a guy.
MK (and Wilson) blades are available with parabolic side honing (slightly thinner in the middle, advantage uncertain, but complicates sharpening a lot), and Revolution mounts (lighter, cushions jump impacts). My best guess is that both are mostly a waste of money for an ice dancer, but I could be wrong.
Unfortunately I haven't tried enough different types of Dance blade to give you a full blade comparison. Plus, I'm not that great a skater.
