I realize my trick vocabulary is probably not very accurate, working on learning the official trick names/combos.
The first one I learned was using ken grip and stalling the ball on the ring around the edge of the bottom cup, I also was able to hop the ball from that position a few times and stall the second more rounded ring.
The first trick in this video shows what I am trying to describe.
Yesterday however I learned them using the special grip, which so far is one of the hardest tricks I've been able to get.
