well i dont know about everyone else, but when i learned, my first thought was which jump to do it off of. I wanted to to it off the smallest jump in the park (5-10) but my friend said it would be easy to just do it off a big jump, so he convinced me to do it off the biggest jump (35-40) because it will be easy to stall out and be in control. he explained that once you can do it off big jumps, downsizing is easy, where sizing up is a lot scarier because of the possible risk. well long story short, it was the second to last run of the day and he said, ok stop being a baby and do it. landed first time first try and didnt even hand touch easier than learning a 3 swear to god. just continually look over the leading shoulder and DO NOT open up. take it to a bigger jump and it will be easier. but honestly the single most important thing for learning any new trick is to want it enough and COMMIT
