Are Tensor Oust Moc 7 Bearings, Abec 9 Tolerance good skateboarding bearings?

Never used the Tensor bearings, or Destructo ones either. For the same money, you can get Pig Swiss. I use them in all my setups and have had very good luck. Bones Swiss are a little less money and almost as good as the Pig. If you want to save even more money and have very good quality, go with Bones Reds. They are a very good bearing for the money.
