I've been trying since GG posted it, and I think it's possible, but with wallride it's too hard to get height, I've came up with a idea, that kinda works, I can get the angle but my p2b isn't getting Height Enough, I'll try some more times...
My "method" to get the angle is to "Sidebump" (new therm?) that wall, instead of wallriding it, it's a mix of Luck and aim... By "sidebumping" it, you can get the angle without losing your p2b height... Think it's a good idea
Good FPS may be really able to land this way... good luck
