TMNT (Stern) and GB.

The ball often has a heavy spin in Turtles presumably thanks to the spinning disc, so some of the typical caroms that happen in other pins happen differently in here. The worst section is the top of the left sling. Ball will come out of the left orbit fast or slow, it doesn't matter, and hit the top post on that sling. Instead of bouncing up/out at a slight angle like you'd expect, it rockets 90 degrees over to the outlane almost every time. I find it very difficult to defend against since it's counterintuitive to want to nudge a ball that is already in a safe area, but that's the only way to deal with this, nudge when it's about to hit that post to try and dampen the spin and keep the ball in the playfield. It's annoying as hell since it's an issue you're gonna have to deal with multiple times per game. Or maybe my level is off by a bit which is amplifying the ball spin, who knows. I'd try to fine tune the lane guide on the orbit if the game was mine, but it's a rental.

GB's frustrations have been gone over many times before. The flipper gap isn't great, but it's not a deal breaker. The magna slings though, woof. While it's cool to watch your ball get frozen in "mid-air" and then thrown in an unforeseen direction, it's not a lot of fun when that unforeseen direction is straight down the middle. Which happens a lot. There's pinball randomness and then there's just being obnoxious.
