Quoted from tslayer71:
So balls coming from the upper playfield are easily cradled with a raised right flipper which I think is normal. Ideas for making this more challenging? Different bouncy flipper rubber, lower flipper bat angle so harder to cradle, offset upper to lower playfield wire form so ball hits lower right flipper in different place?? Thoughts? Thanks!
Pretty sure it's a combo of the angle and the rubber. I don't think there's much adjustment from the feed wireform, and I wouldn't take too many liberties with it, they're not easy to replace.
