Quoted from Mattman55:
Does anyone recommend changing the Lost Mine kickout coil from a AE-23-800 to a weaker coil AE-23-1200?
Here's my thoughts on it. I say "yes" BUT don't castrate your game in the process. The original coil kicks the ball out something fierce and you have to gain control, which is tricky.
A lot of people reduce the coil strength but do so in a way that the ball kicks to the (unactivated) right flipper, then bounces over perfectly so you can cradle it in the left flipper. This makes the game SO MUCH EASIER. Lyman Sheets exploited that in a previous PAPA and got some crazy high score. You can get multiple, multiple whirlpool completions on a regular basis like this.
What I did with mine is put in a weaker coil to prevent damage, but it's still a bitch to get controll again after the kick. If you try to let it bounce off the right flipper it will drain down the center, so you must try to control with the right flipper, which leads to all types of variations on where the ball ends up. It's not exactly the same as factory, because the kick is weaker, but the amount of skill needed to regain control is comparable to the original design.
I have a 26-1200 in mine, which is what a lot of people use to get the easy kickout, but you can adjust the coil so that it kicks out a little weaker so that the ball won't bounce all the way over to the left flipper.
