Quoted from E_N_3:You might want to check the coil on the upper flipper, as i undertand that it is supposed to be a weaker coil than the lower 2 coils, as to prevent it from hitting the ball too hard in to the drop targets, thus cutting down on target breakage. From what I understand, many times people mistakenly replace the upper coil with the same strength coil as the lower ones, which winds up destroying targets.
Fun little fact I picked up from watching the TNT /Todd video on YouTube for this title
How funny, just watched that video last night!
