Quoted from jar155:The game calms down big time after a breaking in period. Games that have seen more play see WAY less ball jumping over the return lanes. The Scoleri targets will always cause some bouncing, that's just the nature of those sorts of stand ups. Playboy and Sopranos have them and they cause hops all the time. The severity of the hops or the reliability of the targets dropping will improve as things break in.
I don't see any problem putting the replacement springs in now if you want a faster break in period, but I don't think that the return lanes are that big of a problem once the game settles in. If you ever saw an Iron Man or an AC/DC fresh out of the box, you saw tons of air balls on those too from all over the playfield.
Agreed. I've been playing a GB Pro on location that has been broken in. Most of the hops/airballs that I still see now are when you miss the left ramp & the ball lands on top of the playfield platics on the left side & rolls down them. As long as you nudge a bit, the ball will usually land back in the left inlanes.
The drop targets are typically no problem as long as you backhand them.
