Just curious, what pin did you decide on adding higher power flipper coils to?

I've owned both of those games... do you have low line voltage, as I can't imagine how those plastics aren't going to get slammed with higher powered coils, especially Fire Queen; both of her target bank plastics suffered badly from ball hits from normal tap conditions; highly recommend (if you have not done so up to now), using nylon or some type of protective washers underneath those to protect them and to raise their height a bit.

Go for it!
