A few tips or rules of thumb...not written in stone.
1. When drying tobacco, it should be damp eough to spring back when squeezed between thumb and fingers.
2. It's better to load too loose than too tight. If too loose, you can fix by tamping. If too tight, you have to empty the bowl and start over.
3. while smoking, SIP the smoke,do not puff.
4. A properly loaded bowl should give resistance similar to that experienced when sipping milk through a straw
5. Different "cuts" of tobacco have different burning characteristics. Ribbons and shags will burn quicker than broken flakes; broken flakes will burn quicker that cubed and flakes.
6. Different genres of tobacco have different smoking traits. English and Latakias seem to produce more smoke than Virginias.
7. The ideal is to have the tobacco to the stage that it smolders, with out going out.
8. There is no such thing as too many relights.
9. Pipes should be "sipped" not puffed.( Iknow this is a repeat, there's a reason for that
)
As I states in the beginning, nothing is written in stone, find what works for you, that you enjoy and stick with it.
