I remember three Polinas who were active during a couple of seasons post Vancouver: Polina Shelepen, Polina Korobeynikova, and Polina Agafonova. They were pretty decent skaters in my memory. Shelepen was two-time JGPF/Russian Jr. National silver medalist. Korobeynikova was 2011 JGPF bronze medalist and 4th at the 2012 Eurioean Championships. Agafonova was 2010 Jr. World bronze medalist and 2010 Russian Jr. Champion.
I haven't heard anything about them recently. Does anyone on this forum know what they have been up to? Would appreciate if you can let me know. Thanks.
