Anyone have any specific pointers for slappy feebles on parking blocks (backside)? I can do other slappies and these look so simple and effortless compared to even slappy 5050s but I can’t wrap my head around where to begin with them. Obviously the front truck is being placed over the block as you get to it but are you putting pressure on your front foot at that point to assist the back truck in popping up to lock into the feeble? It also seems like you need to be moving at a decent speed to make these work.
