Ok, by “that guy” I think you mean Andre Boulay. He is the owner of YYE. The yoyo he’s using is his signature yoyo, the Yoyojam Dark Magic II. It comes with two bearings: a slim bearing for responsive play, and a C-size bearing for unresponsive play. However, seeing that your favorite trick is rock the baby and your favorite yoyo is the fireball, the Dark Magic II might be too advanced for you. You should probably start out with a cheaper, beginner yoyo.
Fixed. I hope you realize that as a new player, he probably can’t bind yet. The ONE comes with 2 bearings, a slim bearing, and a wide bearing for advanced play.
I started out with the DM2 also and it worked great, until it broke, but as I recall the DM2 also comes with a slim bearing for responsive play, and a YYJ speed bearing for unresponsive play. It says so in the description on the product page.
I recommend this yoyo
