Why different flipper coils? School me.

Per manual specifications, I've installed the missing flipper coils on this Twister I'm bringing back to life, and I was wondering why they were different. It seems like the coils would be exactly the same, but that isn't the case. Why is this?

I haven't played the game, but DE/Sega used different coils when playfield shots needed the extra strength to hit a ramp or other shot. Baywatch and Batman Forever are other examples with different coils on the right/left. I owned BF and I understand why they put a stronger coil on the right, it was needed to make the ramp shot to the cannon.
 
It all depends on the playfield. Sometimes there's a far shot that needs a stronger coil on one side. But sometimes there's also a close shot that too much of a coil will start destroying switches/ramps/etc.

My guess, in this case, is that the left flipper gets the stronger coil? I say that due to the height of that ramp on the right side.

Ahhhhh... That makes sense. Thx!

It certainly seems like it would, as that ramp is fairly steep.

The manual specifies a 22-900 (YEL) on the left and a 22-1080 (YEL-GRN) on the right. Even though the physical size of the 22-900 is smaller, is it still the stronger of the two?
 
The general rule of thumb is larger gauge wire and fewer turns = stronger coil because both factors mean less resistance, more current, and stronger magnetic field. So the 22-900 would be stronger (900 turns vs. 1080).

Great info; thanks!

(I tell ya, I've learned a hell of a lot restoring this machine. Its been fun.)
