Micro Mo, is worth the money, but as they said, I would highly recommend the Yuuksta.
A very undersized yoyo doesn’t quite fit your skill now. It would be a challenge. Not too small, but a normal undersized would do if you really want an undersized throw.
Yuuksta is 50mm, an undersized, would be a great throw. But again, what level are you at? Learning the Rewind, Double or Nothing trick level or higher?
For a beginner like as I just stated, a Raptor or Dv888 is great. But if you’re looking for plastic, Northstar and Protostar will do very well if you don’t mind the grinds.
