What I'm trying to say is I've been skateboarding for 8+ years, been to countless skateparks and street spots, and yada yada yada...I have yet to see one Pro, Am, park rat, street skater, or even a poser use tailbones.
Why do you think nobody uses them? Do you think the majority of skateboarders are just illiterate? Nope. We don't need or want them, they only get in the way. If they work for you then great, go for it.
But for kicks I'll ask Mike Maldonado what he thinks of tailbones. I'll let you know.
