Upgraded from an 67" ep comp 1 to a 69" ho omni and progressed handily last year. Skied the course for the first time last year sadly didnt make bouy 2. Im 39 and learned to ski at 5 and slalom by 9 and spent a good portion of teens through 20s on a wakeboard. Weighing 165 and skiing at 34 mph is this ski too big. What benefit should i expect to see with a higher end ski?
