2. Ollie up and land slightly over-rotated the where your nose point away from the ledge. This is easier than landing straight on, and you will gring faster, with more of a flow.
3 It's easier to come off a ledge that has an end to it, but if yours doesen't, don't worry. As you gring and begin to slow down, try to do a small ollie by jumping forward with your board. Don't worry if your tail is hitting while you grind, you can still make your board come off by trying to ollie.
4. If this is to frustrating for you, try coming aff 180.
5. This trick is y also be easier if you have more speed.
