I like the floating feeling you get on quarterpipes, it feels like you're hanging in the air and you can with no trouble grab anywhere on the board. One of the most fun tricks on a QP is the air to fakie.
Airs to fakies are also one of the easiest tricks. All you have to do is ride straight at the QP on your shred stick. I like this trick because of its simplicity. An air to fakie is basically the same thing as straight airing a jump, except the QP shoots you straight up in the air
