no north shore, its got its place, but i fail to see the apeal of riding on a 4" wide wet plank when theres perfectly good dry dirt just below?
big fast berms, getti progressively smaller/tighter down the hill, so the first few you are just rolling through, the last few should require a big heavve on thebars to get th bike into the next corner and allow a lot of pump.
tabletops, and make them progressive, building up to anything upto 6ft tal takeoffs and log landing ramps.
Drop-offs, again some progresivity, start with next to no drop and a long downslope (so faster riders get some air) and move upto a few feet. Then some step downs which require you to lok for the landig a bit more.
Step-ups, lots of fun, very very hard to mess up on as if you come up short your already going fairly slow.
steep roll ins, geting steeper and slippier, teach newbies not to rely on the brakes and get their weight back.
jerms, contrajerms and hip jumps, Phill Saxtena (sp? the 4x track builder) coined the frst two of those. Basicly various combinations of berms/jumps/takeoffs/lanings that force you into shifting the bike arround mid air rather than being a passenger.
