What these dudes are saying! If you skate and can do an Ollie on trany like a quarter pipe, it's pretty similar. It's like in different languages... Just translate it! Very similar, and once you figure it out, you'll know when and where to do it. Trail and error brotha! What helps me is once you get the speed and see where on the waves you wanna do it, slide your back foot all the way back on the traction pad(if you have one) a split second before you go airborne.
Film yourself. then compare yourself with pros. make sure your not slowing down right before you hit the lip. Its natural to want to hit it when its too late. you want to be going up for it before the wave starts throwing out.
