I was reading a mate's "Ride" mag the other day and there was an article on bunny hopping up walls and so-on, However it says start pulling up when your the distance away from the obstacle as it is high if you get what i mean.
I used to be good at hopping but since i got my t-rex i've become rather bad. As for manuels :"> lets not get into that....
Hope this helps, Kieron (Y)
