I havent been able to ski as much as i would have liked this year and I just skied in my first tournament last sunday. I grew 5 inches and gained about 15 pounds over the winter and I am having a hard time to get used to my new body. I realized that I have to work harder behind the boat to run my passes now and was very suprised. Hopefully I'll adjust and get used to it, but man does height and weight affect your skiing.
The added height is an advantage. If you don't want it, I'll take those 5 inches! Keep focused on your technique and you will be rewarded.
