AWESOME!!! I just got my first YYF in the mail (Grind Machine white with trans blue rims and Hubstacks. It’s for Christmas, so my wife won’t let me play it yet, but i’m glad to see that the man himself promotes them on his site.  
Andre,  
What do i do with the rubber rings? I know you can add them to change the weight, but how are they supposed to fit?  
thanks

Great, I have a GM too. You put the rubber rims around the hubstack behind the body rims.

Happy Throwing ;D
