Something about how The pops on Rocky and Bullwinkle are positioned make them quite useless.
If the ball drops into the bumper area via the center lane, it'll generally not hit a single pop, and just roll right straight through.
If it rolls through the other two lanes, chances are pretty good that it'll hit one pop, and be deflected out on a trajectory totally missing the other pops. It's very rare to have the ball sit up in there and bounce between them.
And about the only time you'll get the chance to enter the pop pit is at ball launch. Due to how the gates surrounding the lanes work, they're generally always open so shots tend to orbit rather than drop through the lanes. And through the lanes is the only path to get to the pop bumpers.
So, even when adjusted correctly, R&B pops are pretty poor.
