Quoted from 85vett:
Best way to increase bonus is to collect the lane award (when the F, I, R or E is flashing) on the outlane when flashing. This is important in multiball as you really don't want to do that in single ball play for instance. Just avoid collecting on the inlane (2x the next shot) and if you are going to drain on the outlane move it to that lane to collect. This is your bonus multiplier. After a couple big balls will multiple MB's the highest I've gotten this to was 5x. Don't recall the total bonus but it was really lucrative.
This isn't really the bonus multiplier. The bonus multiplier is awarded from completing the top 3 lanes. The outlane is a total bonus multiplier after the main multiplier is all counted. I didn't test what the max outlane bonus achievable can be, but maybe later. Regular bonus multiplier can go pretty high it seems. Bonus hold will rock!!
I noticed the colordmd rom seems to stop colorizing bonus count after about 30x.
I've been testing the 5 target bank and trying to resolve 'bounce offs' without a target dropping. At first I made it worse, but now it's better. Out of 50 tests just now, maybe 3 or 4 bounced off and it's usually the center target. I will set the coil strength back to normal and see if that helps.
I wish there was a sling power adjustment so I could tone these suckers down just a tiny bit. That's mainly why I had soft coil setting. They have to be the strongest slings in any game I know of. Very fast!
