Frontside 5-0

You ought to be comfortable with the 50-50 and the manual before taking on the 5-0. Approach the object as if you were going to do a 50-50. Pop an ollie and get your back truck on the ledge (again, like you were going to do a 50-50). Instead of putting your front truck down, you want to try to stay in the manual position. This requires more forward momentum and backward lean than a manual, depending of course on the butter factor of the obstacle in question. Just hold on to that grind as long as you can or until the end of the object and come off as if you were coming out of a manual on a curb. A good way to lock into 5-0 grinds is to angle the board out like a smith grind, only pointing up instead of down. This will let you apply more pressure towards the obstacle to keep that back truck in position, and don't be afraid to let your tail drag along the surface (Watch Rick McCrank's 5-0s for a good lesson on this method).
