Question for you solo dancers - I assume the choreography is modified for moves like the one in the Golden Waltz where the man dips the woman? Or are we talking about solo FREE dance, not compulsories? Dancing the compulsories solo would be a great prep for dancing them partnered, or for dance in general. You learn balance and confidence and generating speed on your own.
US solo dance competitions can include pattern dances, variation dances (pattern dances in which the skater performs the set pattern followed by their own steps and same general shape of the pattern as the music continues), solo free dance (with "edge elements" in place of lifts), and rhythm dance at junior and senior levels (ditto).
There is also shadow dance for two skaters skating the same steps of the same pattern dance side by side.
Combined events juvenile, intermediate, and novice consist of one pattern dance and a free dance; for junior and senior a rhythm dance and free dance.
The pattern dance events that are not part of combined events separate "Gold" from "International" level.
According to the handbook
All pattern dances will use “Solo Dance Steps” for all competitors, so skaters are using the same steps. Please refer
to the pattern dance diagrams for the steps to be skated along with the number of sequences, Key Points, tempo
and time limits for Skater’s Choice skating time.
Male and female skaters compete against each other skating the same required steps of the pattern dances. Often the solo requirements use a mix of the men's and women's steps of the partnered dances.
I haven't been paying close attention to the dance selections over the years, but I don't think the Golden Waltz has ever been selected for the International pattern dances or as a pattern in a senior rhythm dance. If it were, I expect that the sections where the women's steps cannot be performed unassisted, the men's steps would be used instead. Or, since it's a once-around dance, if it were used in a rhythm dance, only part of the pattern would be used.
