I would own these guys with the unicycle training i have done lately. Yesterday i did 800 m repeats at the track. I would just spin out and still only be at 14 km/h with the little 20" wheel.
I've also been kicking a soccer ball around a little bit.
There are many things that can improve your skiing. I can balance on a unicycle while pedalling at like 140 rpm and while avoiding the sand patches and pot holes at the Yellowknife track. I can juggle a soccer ball for a few minutes. Balance and body awareness can generate talent.
Remember: make the ball happy.
