So I checked out the different approaches to packing. 3 pinch made sense but when I pack the pipe too tight for the 3rd pinch it seems hard to light and stay lit. I find if I loosen the tobacco in the pipe it seems to burn better. Are there any downsides to have the tobacco packed loosely?
Should draw from the stem like a soda when dry-drawn before lighting after your 3-fill process.
Milkshake thick draw, too tight.
Air draw lightly, too loose.
Practice is okay. Starting over is okay, especially at the beginning of your adventure. Unpack your pipe with your tamper tool into a bowl, cup, or ashtray and re-pack until you get it right.
You know, even on occasion, I underestimate the density and moisture of the tobacco I'm using, and I might pack too tightly once in a great while. Make sure you draw before lighting to make sure it's set right.
If it's too tight, you'll end up drawing too hard, fighting it, and it will be work and un-pleasurable. You'll end up drawing into your lungs too much tobacco smoke as well which is not recommended. Just unpack (cussing is okay if no ladies are pleasant), laugh it off, and start again (and again if necessary). No problem.
