Rach #2 has been used a lot, sometimes with #3.
There are so I would love to see skaters use, sometimes I will be listening to the radio and hear a greatskating piece but never even find out the name. The ones coming to mind right now "Rubies" from the ballet Jewels. Some of Mozart's lesser used works, Choplin's Polinase. La Ginochia could be charming for the right skater.
