There is a rather steep faced jump at our track that is tricky at first, but once you learn how to hit it there is nothing to it. I like to come into the jump a little slower than normal and really compress the bike into the jump (front and rear suspension). Once I am compressed, I roll on the throttle off the lip for a real lofty feal. I also hit this jump one gear higher than I would normally do on a jump of it's size (only about a 35 ft length, but real steep). It is purely a timing thing.
I can't complain about this particular jump b/c I'm the one who built it in the first place, hehe.
