I laid mine out 60*5*40, and left it out of box. I don't usually have a problem getting the ball around the corner, so I'm around the ball a bit. Don't have exact specs, but when I go to get on it, this ball can create some angle. I do need some oil to push it down the lane, but it's really useful when I see some volume because the cover reads the pattern well, but it recovers so well when it hits the friction. It also carries like a Mack Truck when it hits. Seriously impressed.
