I went Medvedeva, Nagasu and Kostner.
Medvedeva is a no-brainer.
Nagasu also seems like a reasonable bet given her recent success in training as posted by Tom Z and herself on instagram. Competition is different I know, but I want to believe she is very confident now and can deliver.
From her last competition, it is clear that Kostner can and will garner high PCS regardless of jump content. I therefore give her the edge over Higuchi.
