Although I find it difficult to smoke a pipe with too tight a draw or too open, I do like a range. I feel more like a driver that adjusts to the car, than a driver who prefers just one type of car. When I get a new pipe, I enjoy learning how it likes to be smoked, instead of trying to make the pipe conform to me.
A tighter drawing pipe tends to smoke cooler because it forces me to slow down. An open draw tends to stay lit better and allow for breathsmoking, where I just passively let the smoke drift in and out. Either way.
If I was pushed into an either or situation, I would probably cast my lot in with the open draw crowd, just not too open. I hate sucking ash and tobacco flakes through the stem.
