Depends on the location of the lower sling post in relation to the flippers. It's just different on different games. If you can hit the ramp shots with the flippers they're probably fine. You could adjust the flipper angle but that may make making shots harder. Could you post pass before you did some sort of adjustment?

I just tried mine and it is definitely harder. I can do it but it takes a more deliberate flip to get it to the other side and it usually heads over a bit fast. Takes about 4 or 5 flips to get it just right, otherwise it just hits the post and comes right back to the same flipper.
