Black panther's are pretty fast.. Bones bearings are some of the best ... Both of these bearing brands for sure if you looking for speed,quality durability.. As you know thou the best are always expensive for a reason but probably worth it....
If you can spend a lot of money, bones swiss ceramics are the best bearings out there, but run around $120-160. Any bearings that cost around $20 or more are fast, but brand-wise the highest quality are bones. By standards, bones reds are the highest quality for the price. Almost every skater uses bones reds. They cost $20 and are better than flip, panther, and other bearings at the same price. They are quite a lot faster, and a lot more durable as well.
