Stepchild jib stick vs signal park rocker?

I am always in the park on rails and small jumps, so im just wondering which board would be a better fit for me? I want THE FLEXIEST BOARD on the market. Like i want this board to be a noodle. Let me know what you think i should get! (i currently have a rome graft and its pretty solid but im looking for a more jib-specific board)
