i am ‘good’ at rails i’d say, but my jumps lack a lot. i can spin up to 540 on a jump is my only trick, i can do easy grabs like safety, blunt, and japan but i can not do anything else, just wondering what i should do offseason/early next season to progress

My hips have been getting super beat up on rails recently and im wondering if anyones tried something like these and if they're any good

I know I’m doing something wrong but should I try it on a bigger jump?

I was wondering what the best size is for a backyard setup. I’m looking to build one I just need some ideas for the dimensions of the ramp/run in
