I only hit it once so I can't give too much info, but it was actually surprisingly fun. I thought landing on it would be awkward but it's really not; trying to get off of it made me feel like a fool though haha. The kicker was pretty nice and of decent size. As for the flip rule I can't say for sure, I didn't really wanna push anything on my first hit but I saw guys going inverted fairly often, I think they just tell you not to do it again. It was fun for free, but I'm not sure how fun it'd be when you're shelling out $10 for three hits or whatever the hell they want.
