Tom, honestly you have to start trying new things.
Im not trying to bag you out or anything. I guess what im trying to say is that you've been riding a year and a bit, and your best trick is a double tailwhip. It's really not that hard to progress.
Ohk sweet. Ah well i spose everyone starts somewhere. I just find it odd that you progress this slow. Everytime i ride a learn a new trick and just confused why you dont progress.
Stick at it then dude.
Exactly what Jamie said. Watch a video of someone. See something you think is rad. Then go do it.
For example i saw Manzie or Billie do a hang 5. So i set out to learn that trick, even if i did go over the bars about 1000 times in a week.
Im jesus at them now. Still cant compete with Billie, Crossfoot fakie nose manual
