My HO A3 was doing just that. I had to take a year off because of a shoulder injury and J.O.B. (Just Over Broke). When I started again this season my ski was doing the wheelie all the time. It never did that before. I thought it was all me but I also now weigh 20+lbs more. I moved the binding 1/8-1/4" forward (one notch) and BOOM no more wheelies and more acceleration, speed, and turns better than ever. TOTAL CONTROL~~~> Just my $.02 worth
