Interesting comparison. The two in the grey are Australian, the red is Austrian and green is US. Alignment is playing a huge factor here in the way they ski. No two ski alike. The two Australians have the best set up and are skiing with the most consistent turns and most freedom and relaxation. Even the Australians have some differences in their techniques, but are the most efficient of the 4. Congratulations to them. The other two demo skiers are compensating and adjusting for their alignment in almost every turn. The green jacket skier is the farthest from connecting consistent, round, controlled turns.
