whats the difference between the small bearings and large bearings?
Well aside from the obvious size in the bearing they differ in play slightly. The large bearin gives the yoyo a wider gap and allows it to have more string wraps. As far as the small bearing goes, the only advantage i know of is that it would prevant the string from coming off the side of the yoyo better. Persaonally I would reccomand the large bearing.
Search for my Dv888 review on this forum. I believe I go a little bit more in depth there about bearing sizes.
Small bearing tighter binds less gap large bearing wider gap
small bearing yoyos can be a tad snaggy, but they generally can spin longer and spin faster. you can also do some neat “snag” tricks like Bad Chinese Food
