Bones bearings are well known as the best for many reasons.
They have an amazing price range and they serve true quality.
If your going for a good price, check out Bones REDS. $18 at most stores. They serve as a son to the Swiss bearings and they are well priced.
If your going for quality and have money, try either Bones Swiss, or Pig Swiss.
If you ride a longboard consider Bones Swiss Ceramics. These are the BEST bearings out there but i do not recommend them for street skating or tricks because the ceramic balls (lightest, smoothest, and water proof) will shatter on enough impact!
Ceramic 8-ball bearings are the best bearings out there.
Bearings are classified on an Abec system 1,3,5,7 and top being 9. Bones bearings are recognized as being the best.
they're basically the best bearings money can buy
why do you want to break them in... fresh bearings are the best.... but that's my personal opinion
Bones Swiss Ceramic.

in longboarding bearings don't make that much difference (providing they are clean and oiled) unless you are racing slalom or downhill were every 0.001 of a second counts. so cheap well made easy to clean bearings are the best e.g. bones reds or bilitins are great simple to clean and change.
bones Swiss are the best bearings.they are on the expensive side but are worth it.
