The spine ramp is one of the best ramps I've ever skated. It's mellow transition makes it easy to progress. The metal surface makes it fast and fun. It seems to be more sturdy than most metal ramps. You don't get that pro wrestling ring/ trampoline feeling like most metal ramps. The coping is set perfectly and grinds real nice.

It's also partially in the shade at times which is very nice for skating in Missouri. If it were twice the width I'd move to Joplin.
