haha, So I switched my “black” broken in yyj size c bearing into my yyf die-nasty. Suprisingly, it spins Over 30 seconds longer. It plays better and it just is better and is a little quieter. Just thought i’d share that with you guys.
Nice…this is kind of a pointless thread, no offense.
Just because you’re a fanboy… LOL JK. 
Work on your throw, Chris.
Not true.
i slapped a yyj bearing in my genesis… priceless and i put orings in the side and its so awesome
If the yyj bearing is broken in and the die nastys wasn’t its normal that the bearing spun Longer
