Ive been skating handrails for some time now and have nearly all basic regular tricks down (50,5-0,crooks, fs smith, bs feeble, lips, etc.) except for BS smith and FS feeble, not sure how to really get into it right, like i can lock in but cant slide them which is scary due to my park having no flat-bar so i am trying to learn them on a 3ish stair park rail and end up getting pitched to the bottom of the rail.
