Just got the Bass Boost yo yo. Spins super smooth, long spins untill 2 or more strings hit the bearing. The response rings have a way of slowing down the yo.
I decided to put in flowable silicon.
The bearing is very smooth , does anybody know the brand? the size is 250x500x.187’
The Bass Boost is very similar to the x-convict. has a wide profile. The mass is not concentrated on the outer edge.
Feels good on a throw.
