They're great when you get them right, for each side of your deck, you need to wrap one coil clockwise and the other counterclockwise, I see your atty has a centerpost block so 4 post holes, it makes it a little bit harder to do, but not impossible. I did it once on my mutation x v3 & found that it works best when you have the lower leads of the coils going into the centerpost block. It's a bit harder to get them fully touching but it's possible. If the post holes were 1-2-3-4 (neg, pos, pos, neg), it might be easier to get them fully touching if you put coil 1 in post holes 1&3 and coil 2 in holes 2&4.
