The one where Krystle feels guilty about not playing in pinball tournaments and has a question for people who wear headphones while they are playing pinball.
The simple version of my answer to the headphone question is I use them to help prevent overstimulation while playing at tournaments. I usually play no music at all and use only sound canceling if available.
The longer version of my answer may need an episode of The Meltdown Pinball Podcast to hash that out.
Fun With Bonus is the home of the semi-coherent, misguided ramblings of professional and amateur pinball players.
