Quoted from Rokablly:Just took off my Cliffy's for the Scoleri Bros targets. It was apparent they were causing air balls. The ball would literally jumping over the air ball protector I bought for the 2x and 3x targets on the sides of the left ramp.
I had to do the same as well. They were causing ridiculous air balls and even hitting the glass occasionally. I tried adjusting the height of the targets slightly to compensate for the thickness of the cliffys and allow for a smoother transition as the ball rolls over the targets. I fiddled with that for a few days and it did help quite a bit but I'd still get the occasional air ball...enough that it took away from the gameplay. I finally gave in and took them out.
Looking back now, just the fact that you're adding this edge that the ball has to pass over at high speeds right in the middle of the playfield actually makes me wonder how some don't have any issues with them at all.
