It's slightly bigger than my dads other obrien competitor, 67.5 (another ancient ski) so I'm gonna say 68. But it's a very stiff competition/tournament ski. I'm still new to the slalom world so there's no doubt in my mind I'm not using it right or to its potential. Ski won't let me roll on edge at all. I start to lean and it stands me right up, never experienced that on any other ski? It digs so hard 50% of the time the rope gets ripped out of my hands @Wish
