I really dislike it when any skater repeats a program, period.
I don't see anything wrong with keeping a program if the skater feels the need to make it better and they are not yet satisfied with it. Some skaters got injured and didn't skate with it all that much. Shen and Zhao often re-used their programs, they only skated four season where they didn't re-use either the short, the free or both.
I don't think there's any chance that V/T will have the same music, based on the Mozer interview translated by quiqie in GSD, but Mozer did say that because there aren't going to be big changes before next season, they'll keep the new lifts they learned this year and the basic element layout.
The piece is seventy-five minutes long...[l]ong enough for an idea to be developed, but not so long that one starts to measure the number of seats to the exits with desperation if the thing doesn’t work" -- Marina Harss
I'd love to see Zhiganshina/Gazsi keep their FD but I'm also really excited to see how they will top that.
Would love to see Carolina keep "Bolero" and Ashley Wagner bring back her "Pollock" SP from last season - was a stunning program!
