what I can't figure out is why it is so so hard to hit the left ramp/loop consistently. I can hit the left ramp in diner 10 times in a row, but the loop in BSD - if it's 3 times in a row it's amazing. It's somehow out of the sweetspot of the flipper. BSD would be a lot easier if the loop wasn't so hard. And it happens often enough that the ball rolls back down because it doesn't have enough speed.
But I get the comparison to Taxi and probably Diner - two ramps which return the ball to the same flipper for repeated ramp shots and this enormous obsticle in the middle of the playfield which you have to avoid at all costs. And the jet bumpers behind the obsticle.
