Ok, just been out for a half hour blast.
I've just managed to go an extra half foot than before so I'm a bit happyer now :P
Ok, front wheel right at the edge of the ledge and then one very quick small low kick to the edge, no hopping, and Lunge like hell! Land pushing forward on the bars for smooth :S
I also found a new technique for wheelie hopping. I now start lifting the front wheel with my bad foot rather than lift and kick with good foot :)
