The Vortex is O’Brien’s wide-body pair, designed for super easy deep-water starts and big, carving turns. The extra surface area reduces drag and provides a huge amount of lift to get larger skiers up on plane. The large surface area also allows for skiing at a slower boat speed with less effort. If you are in doubt about getting up on a pair of skis, go with the Vortex combos. They are as close to a sure bet as you will find.
