The key I needed to remember that helped me relearn is that you kinda need to jam it forward, kinda like you’re going to shoot your board out. Just a quick forward jab and you pop right up there. Oh, and mentally aim it down the length of the curb. I hit trouble when I was kind of trying to slash it like the top of a bank, you want to carve in, pop forward and sim down the curb. Before you know it, you’re on top grinding the length!
Hope that makes sense, best way I can describe it.
