So I only eventually managed to get to the men's practice this evening, but I did get to see most of the main contenders.
The Twitter reports are pretty accurate for Hanyu, some falls on quad attempts, but equally as many well-executed ones.
Kozuka didn't do any jumps in his run through, but there were some lovely jumps afterwards - the ones I caught were mostly 3As. (And some spectacular falls, he definitely gets the prize for best falls

).
It was my first time seeing these skaters skate live, and the difference in SS of Hanyu and Kozuka compared to the rest of their warm up group really stood out to me.
Mura - Opening 4T attempt, 2ft, and I think tripled (but I'm not entirely sure - I was a bit busy being annoyed at the people in front of me blocking my view and too distracted taking photos of Yuzuru standing at the boards to notice that anyone else was on the ice...), nice 3A, stuck a combination on to his last jump, almost fell out of it.
Fernandez - Nice opening jump and combination (I didn't write down what they were at the time so I can't remember, but I assume 4S, 3Lz-3T), somehow nearly managed to fall going into a spin, step out of 3A (possibly 2ft, can't remember).
If anyone has Team Australia practice reports - Brendan or Brooklee or both - I would be most grateful.
Kerry - Fell on opening quad attempt (tripled iirc), then didn't attempt any other jumps in the run-through, but I saw some nice jumps afterwards. (Particularly 3A, I think). I enjoyed his performance.
And because he impressed me, I wrote down that Alexei Bychenko had a lovely 3A and 4T, and a good combination (3F-3T, I think).
