Hollow Knight charm builds

What is your favorite Hollow Knight charm build for certain bosses, traversing the map, fun, etc? Do you ever overcharm?

One of my fave builds mostly for bosses is this unga bunga build that consists of Longnail, Mark of pride, Fragile/Unbreakable Strength, and Quick Slash. Though for certain bosses that do double damage, i switch out Quick Slash for Fragile/Unbreakable Heart and Sprintmaster cause i kinda like the small speed boost sometimes. I only really use overcharm for godmaster, that or boss practice.
