Sorry, the grammar there wasn't very good.
I used to use a basic Coronation Ace for Dance and Free.
I changed to Coronation Ace Dance when I decided that I was getting too old and too many injuries for free. Yes, you can do jumps, etc. using the dance blade, but really it didn't feel as safe to me with a shorter blade (bad landings?). I had other foot problems which convinced me that jumps were a bad and painful idea. I do know coaches who demonstrate jumps, etc. in dance blades with no problems. You'll also see some free skaters with some specialist short blades. Personally I've found dance blades much better for dance once you get used to them. I've had other dance blades over the years, but have gone back to Coronation Ace Dance - probably driven by availability and price.
If you're doing a mix of dance/free then I'd go for the standard blade. If you're really going to do dance alone, then get the dance blades.
