there is really no pipe tobacco that will satisfy you with the level of nicotine that you are used to getting from cigarettes
That is the true-est statement in this whole thread ! I have been hunting for months.
NSFisher is the closest, imho, in what I do as well. Kendal's Kentucky is my go-to since it's a fine shag cut, loads easily in a small bowl for a 10-15 minute smoke and has a nicotine punch that gives me, a 30+ year cig smoker, the dizzies on occasion.
The threads Philip posted are great to explore as well.
However, I have come to the conclusion that the biggest addictive factor of nails is not just the nicotine fix. If that were the case, gum, lozenges, patches, etc would have worked for me in the past. And none of them did. I am getting more and more convinced that the biggest challenge is the oral fixation (let's keep it PG-13 on the comments), combined with the feeling to be able to inhale smoke deeply in the lungs. I have actually found that a good eCig seems to be somewhat helpful during the day. In the evenings, the pipe has proven to be more than sufficient for me lately.
Good luck, I can attest it's a tough road :puffpipe:
