Hey look what just popped up on SkaterHQ, an inline wheel with a solid core. They look pretty strong, has anyone ridden them?

There are people around were I live who scooter, but they're all like 5 years old. I used to have a bunch of people who I rode with at my local but now they're all getting into BMX. So I still ride with them but it's not as good.
