You should know how to 50-50. Come up to your grind and Ollie like always... Actually well I should tell you what the grind is. You grind with your front truck in like a smith reverse kind of thing. OK come up Ollie then land with your front truck on. Your weight should be quite equal but a little more on the front so your back doesn\'t touch the ground. Grind for a while then just like slide of or Nollie off. (This trick is named after Willy Santos since he made it up)

Good Luck!
