So I recently received the new updated Popstar from the 2016 mystery box. It’s a fun throw, pocket friendly but it was missing something. Its weight seemed a little too light so almost felt like it lost spin quicker than the C3YYD Token. After messing with it I decided to try out a concave bearing with it… definitely the way to go! I had a easier time with keeping the Popstar straight and stable with the concave bearing (I’m still learning so others might be much better with the stock CT bearing). Overall after swapping to a concave bearing the Popstar becomes IMO more forgiving allowing me to have more spin time for string tricks. It’s now my daily.
Just as a comparison it’s smaller than the Token and the texture is more like very very very fine grit unlike the polished smooth feel like most other yoyos.
