So if you can see it in your head. you have one of two ways to go here.
1) find a jump that has the right hang time and distence. man up and go for it.
2) find a safe place to try it at least once b4 going to the hill. diving board or a foam pitt.
If you dont have ether one of these you may have to learn old school. By building back country pow jump and work your way up to it. the other option is wait till the end of the session and just go for it and if you get hurt you got 6 months to heel.
I dont know what tricks you can do so I dont want to just tell you go do it. its a risky trick and you should have all your exit tricks ready for if something goes wrong. if you have never done dub back you may want to start there. dubs are a big tricks and you should not have to ask for to much help if your at the level to be doing this trick.
