Ha, how did you know where I buy my boxers? my frustration comes from buying pipes labelled group 4 and having them range from .75" diameters and 1" depth, to 2" depth, to .80" by 1.2" etc, etc... without knowing the actual sizes, the group numbers rarely give me any insights into what the size of the pipe is. Yeh yeh yeh, I am kind of Rainman-ish OCD when it comes to sizes. After years of smoking, I know that I want my Virginia and VaPer pipes to come in smaller diameters of .70-.75" wide, and my blended mixes to be smoked in .80+. So, it kind of matters to me. Most places do give actual pipe sizes, (metric-only people sort of bother me too, but just slightly, having to use a converter) and if someone posts group sizes for non-Dunhills, it doesn't exactly ruin my day. I just move on to better vendors. But, I thought it worth mentioning, because maybe some have the same perspective that I do. So, just sharing my thoughts.
And, I become very Rainman-ish when my wife asks me about how much pipes costs... "'bout a dollar, yep, yep, 'bout a dollar." :
