Hardest thing about smoking a pipe

[Neuromancer]

I smoke both cigars and pipes and have never noticed a problem going back and forth, day by day, however, I'll stick to one or the other on a daily basis...if I start with a cigar it will be cigars for that day, if I start with a pipe, etc....and I really don't notice one affecting the other taste-wise, and pipe tobacco-wise I smoke them all (Eng, Aro, VA, VA/Per)...just depends on my mood of the day...
