Going back to 0.5 after trying 0.3mm is like going back to dial-up after fiber, I just can't do it.

Good coaching beats a good lawyer sometimes.

Is it crazy that I've started treating my starters like moody pets? @sam_anderson Your buddy Mike's story is exactly why I keep a dried backup in the freezer. I had a liquid starter go bad once, got that same purple hooch smell, and tried to revive it with a sugar wash. Big mistake. The dough came out flat and sour in a bad way. Now I just grab my dried backup, rehydrate it, and it's like having a reliable old friend around for when the main one throws a tantrum.

Yeah graphite is fine for light duty stuff but that's not a permanent fix. The real problem is the hinge pin or the barrel itself is wearing down or slightly bent, not just dry. Over time that graphite will just wear off and you'll be right back to shoulder checking the door. If it was truly just dry and sticking, sure, pencil works. But nine times out of ten a sticking door means the hinge screws are loose or the frame has shifted from settling. Pencil lead isn't gonna fix that. You'd be better off just tightening the screws and maybe sanding the door edge a little. That's a more lasting solution.

This is literally what happened to me with those same SA90s a few months ago. I finally get the hype now after hearing how clean my drums sounded.
