In the field of skiing and snowboarding, What is the meaning of this sentence:
[He manages to get good snow throughout this run and it will pay-off with the judges, who look closely at choice of line as one of their criteria.]
I can't understand the highlighted parts!
Can you kindly explaing to me "How do they (choose) lines" and how judged? It will make a big difference in my understanding to the whole episode.
Thanks a lot.
