you're kinda breaking it down real simply in a way where it seems like you're looking to inhibit creativity.
a 3, 5, and backflip all have endless variations of ways you can cork them out, shifty, grab.....
Noones going to tell you to spin or flip more, but can you grab a mute in your backflip or truckdriver in your 3's? Have you ever tried carving one way and spinning the opposite direction.. How about learning 450's on jumps and tokyo-drifting your way down the landing..
Freeskiing's limitless until you deliberately try and put things in a certain framework. Break free from that and understand that you can always progress and it may have nothing to do with you being a pussy, maybe it's just you not allowing yourself to see the full potential of freeskiing because you're deliberately putting barriers on it.
