The rocket air feels a lot more inconsistant than in skate 3

I have played skate 3 for a long time and the rocket air was a lot easier to do. All you had to do is pull the right stick down and press and hold a trigger, then the other. But on skate, you have to pull the right stick down and press and hold both triggers at the exact same time. Most of the time I end up doing a crail or nose tailbone instead of a rocket air.
