360 flips is THE trick in that category. It looks difficult, but is actually easier then doing a genuinly good kickflip
Definitely not a universal truth, I've struggled with 3 flips for two decades now.
One day I'll land them almost every try, the very next day I'll land 1 out of 50.
Whatever the knack is for them, I just don't have it, or at least I can't keep it for long periods of time.
My kickflips are always on point tho!
I said it in another thread, doing a
good FS nose slide is way harder than people give it credit for being.
