Given the erratic timing & frequency of my pipe time, I'd say 25-50g per week. But my most recent estate pipe showed up & was less of an Ashton and more Pipe-a-saurus Rex. I usually stick to smaller bowls, but this thing has it's own gravitational pull. So far I've lost a tin of Mac B' s HH Highland, 1/2 tin of Royal Tudor, & 3/4 tin of Black Ambrosia to it's clutches. So obviously, that average is going up. Anyone seen my dog?
