Pipe smokers vary in their nic-level preferences. I'm curious, however, if you desire even a slight 'nic hit,' even if you prefer milder tobacco. For my part, I enjoy mild to medium-strength tobacco, as I smoke in order to relax, and a mild nicotine hit certainly helps in that regard. The strong stuff I can certainly do without since it tends to give me nausea. But if the tobacco is too mild, I'm left a little unsatisfied.
