I cleaned my drop targets & put on new springs, I get fewer airballs. It still happens though sometimes. Not really an issue though, as the ball does often land on the rails & into the missle launch, so it works out fine.

Favorite mode is usually meltdown.
Hardest mode, Battle Tank can be tough but its doable for me. Pursuit I can struggle with, alternating hitting ramps.
Its funny how some timed modes can mess with your head & skills. When time is running out on something.... klunk, klunk, klunk. As soon as the mode ends, I can hit those same shots all day!

Falls into the left ramp? I believe without the deadworld mod, the ball lands in the deadworld then the crane picks it up right away, & should drop it at the far left (to the left of the left ramp). If your ball is falling onto the left ramp, that doesn't sound right. Is your crane ever getting used?

I highly suggest getting the deadworld mod, especially if you are about to tear everything down anyways, this would be the perfect time.
