And the grease is part of the putrid rancid bacteria that'll make you sick and kill youLike some Ol' Wiseman said....play them ol' flatwounds after eating greasy fried chicken and garlic bread and don't ever wash your hands before playing. That grease is part of the funk!
When I was using flats regularly, I could take them for a couple years, and even though I like dead flats, I didn't like them THAT dead. Now that I only use them occasionally, I could probably leave a set on indefinitely.
