Riding switch is the opposite of what your rider is used to. If you have a regular stance rider, then switch would be the goofy stance for them, and vice versa. When you do switch tricks, you get more points than what you would normally get for doing it in regular/goofy form. For example, doing a Kickflip (regular) results in 100 points, but a Swit...From: MMStick

By holding R or L to 90 degrees while ollieing onto a rail, you can do a board/lip slide. To differentiate between the two, a lipslide is when your back wheels go over the object before you start the grind. In other words, if you are on the left side of the rail and want to do a FS lipslide, hold L to 90 degrees then grind (your back wheels will go...From: ljianyih

Manhattan, from the st...From: Taurus Lefone
