Shorter, lighter people honestly have a bit of an advantage in vert skating where the size of the ramp makes up for their weight and strength potentially not giving them as much speed and pop. Being shorter allows you to spin faster, and being lighter allows you greater tolerance on less than perfect landings where a larger skater probably would have gotten wheelbite and ate shit if all other things were equal. There have been kid skating prodigies doing NBD shit for awhile now. Mitchie Brusco, the guy that landed the first (mega ramp) 1260 started super young and I feel like with Nyjah and Yuto dominating competitions, skateboarding has kind of entered into an era where the big medal winning skaters are all savants that started skating when they started walking like Olympic gymnasts.
