Quoted from chadderack:Ramps are pretty flowy, but beware the ramps because of the aforementioned fast ramp returns. When in doubt, flip early!
The returns are actually slower than you think due to the wireform zig-zags, the ball kind of floats down towards the flippers and then WHAM zips right past. Holding the flipper up for a sketchy rolling pass was the only thing that worked for me consistently. Combos are brutal.
