I am 6'3", 190 (down from 225), and because of my beginner course running at slower speeds I only considered the 67.5. I ski with 3 people with s2's. brian, 6'0, 185, beginner course, 67.5. Mark, 6'0' 185' expert, 67.5 ( he liked the 66.5 a little better, but is my age, and has a bad back, and decided to go with the 67.5). Kevin, 6'1", 195, beginner, 67.5. But buski, you are lighter, younger, and you already have a 66.5, and will undoubtedly improve on it.
