"SDTM" KISS Head Correction:
No one needs to reduce coil power, switch coils, or lower lock out time.
Here is an old tech trick:
If you use a small ramp protector inside Gene's mouth, you can redirect the pinball to the left or right however you wish.
Pick the side, and make small bends as necessary.
You can even use a piece of aluminum sheet metal, if you do not have one. Cut it with tin snips, use bent pliers to shape, and file the edges. Mount by flat screw or profesional epoxy.
This requires little modification.
It prevents SDTM.
It will not be seen, if done with aesthetics in mind and a bit of care.
