How much hopping adn Trials should you be able to do when Doing Street?

Doing gapping things, flips down stair sets, unispins up things, rolling hops to grind. How high, how far etc… should you be able to hop when doing street?

Also should i learn height or length first for rolling hops? How should i learn it? Riding to curbs and hopping up them just hopping as high as i can on flat surface?

Sorry if this info is a bit lousy, its just because im louzy rite now -.-…

You should be able to jump and gap pretty well, or else your just a street/flat rider.

Kelly Hicman won the NAUCC 08 trials competition with virtually no practice in trials lol.
