IJS has destroyed pairs even more... . Here's my two cents about choreo jump...how many delayed Axel do we want to see?
If the ISU is going to propose this, they need to give choices to skaters.. for instance, they can choose between a choreo jump, a choreo hydro blade, a choreo spiral, a choreo set of twizzles etc so that skaters select something they do well and fits the program
I am not disagreeing to @Mathman conclusions but I sincerely think one less jumping pass will be good.
If they resemble those of bygone days from Robin Cousins, Charlie Tickner, and Toller Cranston... then I want to see a whole bunch of them. I just realized I'm talking about the men because that discipline interests me more, but off the top of my head I recall beautiful open axels from Peggy Fleming and Dorothy Hamill, just to name two women.
But a choreo jump could have options beyond a delayed axel. A big open airy waltz jump could be cool at the right moment in a program. And, I also approve your suggestions as to other choreo elements to substitute for a jump. I think Adam's aerial/butterfly move merits being a standalone choreo element, for example. If he could incorporate that into a sequence of butterflies... that would be AMAZING.
