Quoted from tampa12:I added the upgraded coils (needed to cut coil diode) because Avengers ramp shots got too many rejects and default flipper power settings were max out. I also have the coil fans but they only make the flipper coils maintain strength not increase strength. If you get ball rejects then upgrade but it will void your warranty.
*1 month later: I have no regrets in fact pin is more enjoyable and faster. No broken plastics or electronic issues to report but did lower flipper power settings a bit.
*Note I'm a repair tech and have 10+ years experience in fixing electronics.
