I'm working on a standard Addams Family pinball. It's in decent shape but the lower left flipper shoots harder than the lower right. After investigating and tweaking the EOS switch on each flipper, the right flipper still doesn't have enough oomph. The left flipper has almost too much power and is shooting the ball over targets and making the ball fly around the playfield too quickly. I looked more closely at the numbers on the coils on the lower left and lower right flippers and the lower `right flipper has a FL-15411 coil IMG_5745 (resized).JPG

and the lower left flipper has a FL-11629 coil IMG_5744 (resized).JPG

The machine also came with a spare FL-15411.

It looks like is someone switched the stock coil on the left flipper for a more "Powerful" blue coil with less winds.

Should I put the stock coil back in the left flipper?

Should I purchase a matching 11629 coil for the right flipper?

Should I get 2 new coils with slightly more winds than 11629 but less that 15411?

I found this flipper coil chart here: https://www.flippers.com/coil-resistance.html

FL-11629 WILLIAMS FAT 4.0/133.0 23/32 800/3000 Flipper Coil (50V) (Blue - strongest - 5/5)
FL-11630 WILLIAMS FAT 4.7/161 23/30 600/2600 Flipper Coil (50V) (Red - medium strength - 3/5) - Wico sub 04-0718
FL-11753 WILLIAMS FAT 9.8/165.0 ?/30 ?/2600 Flipper Coil (50V) (Yellow - weakest - 1/5) - Wico sub 04-0720
FL-11722 WILLIAMS FAT 6.0/160.0 24/30 600/2600 Flipper Coil (50V) (Green - weaker - 2/5)
FL-15411 WILLIAMS FAT 4.2/150.0 Flipper Coil (50V) (Orange - stronger - 4/5)

What does everyone here recommend I do?

Thanks!
