Jump, I feel like there are way more options when you factor in:
- Grabs
- Mixing spins with flips, i.e. cork, rodeo, misty
- Tweaking of grabs, i.e. tweaked japans, method grabs (tweaked safeties), bow-and-arrows (no matter what Steve Stepp says, they're ill).
- Steeziness/afterbang - You can have this on rails too, but DAYUM. I love seeing a rider throw a nice jump trick and then STOMP the hell out of the landing.
Idk, I LOVE both, but I'd rather see an insane jump trick than an insane rail trick. Just more potential for "WOW' factor imo.
