thinking about going with green ball axle bearings

sound like the majority of you all have good experiences with these bearings. I will probably go with this setup. I am a rookie when it comes to this stuff. I am 20 years old and doing up my scamp with my father i was normally into imports and everything so im not familiar with this sort of stuff. You know the books for dummies. Well this needs to be an axle and rear end learning experience for dummies. I hope you guys can understand that i am new to this stuff and lots of help is appreciated.

Thanks,
Joe
