Thought I would share this. I just discovered this guy's channel on YouTube. His name is Kenny Sharretts and he's giving a lot of good advice in his clips.
I noticed in this clip that he's doing something that I just figured out a few months ago- When it comes to fine tuning, instead of tapping at each lug like we are used to doing, just flick the tip of your finger across the surface of the head. This excites the head as a whole a little less and gives you a little more accurate idea of where the pitch is at one specific lug. I figured this out by using my finger nail to lightly scratch across the surface of a coated head, but he's doing the same thing with the pad of his finger on a clear head and it still works.
