This tiny French clencher barely holds 2 coins but smokes slower than a bulldog that also holds 2 coins a little better with a wider, shallower bowl. 3 coiners seem to be the same; a tall, narrow billiard gives me a fairly long and satisfying smoke that others don't.
You are right, a 3 coiner will make me seriously reconsider packing another bowl, and usually you end up splitting it into two sessions if you aren't committed to sitting around for the better part of 2 hours. I rarely fill those to the brim anyway. One *good* pipe session is usually enough for the day or week and lingers for a while.
As a former heavy cigarette smoker, it's a very different thing and not quite addictive. Like, it's nice and pleasant and I get a little bummed and bitchy when I don't have the time, but it's the quality of the session that matters and going a few days or weeks without isn't like quitting smoking.
