Love mine.
But I like the question! I happened to have been thinking about this a bit myself lately. Why do I love it so much?
I don't know what makes it such a pleasure. While I'm smoking it, I'm not "admiring it's shape," just smoking it. So it's not that there's some psychological predisposition for liking it, not for me. Maybe the next guy. I didn't buy it for its style. In fact, the Canadian shape actually never appealed to me. So whatever it is, I just really like that pipe. It satisfies me more than my other pipes.
The only time it fails to please is when I've smoked it too much, not let it rest or not cleaned it -- and even then, I still reach for it, in spite of knowing I should rest it.
Cooler? Well, it is cool. But I sort of attribute that to how I smoke it, how I smoke any pipe. Coolness, for me, is a consequence of something else I'm doing as I smoke. Like most, I think, I tend to keep it on low burn, trying savor the flavor. If I go too fast, the taste changes. And if I hear sizzling, that means it's gone bitter, I'm past just scorching it, and I'm about to get a draft of moist bitterness in my mouth. If that happens I'm scolding myself and taking a break for a bit, let it go down... though it seems once I've gotten to that point, I'm not going to enjoy the rest of the bowl. It's ruined.
I don't seem to have that with this one, no. But... I only have just the one Canadian. So I can't generalize much from it.
Any of my pipes that get hot, I feel as though I'm wasting tobacco. And to milk them for flavor, to tease that flavor out of them, I incidentally keep them from getting hot. I guess. So maybe its coolness is more a factor of being in tune with what I'm getting from it, not consciously controlling heat but without thinking about it, making adjustments to get that cool, dry, flavorful taste; and not a built-in factor of the pipe. I'm doing it.
It sure *seems* I don't have to nurse this one much. I have another Sav (my Canadian style pipe is a Savinelli), a 198 KS Author style Sav, that I have to be more aware of it, seems to me, than this one. Of the two, I like the author shape, I like the way it feels, but seeing the two on the shelf, I go for the Canadian.
Is it just because the KS (king sized) has a lot more ember in it? Is that why I'm more conscious of tending to it? I dunno. Maybe. Seems I can get carried away with that one pretty quick and then it takes a bit to tame it back down, un-stoke it, seems to me. Vague impression.
Without making some scientific study, the most I can say is, I love my Canadian. Never set out to own one. Don't know if the next one would be as good as this one. All I know is, I enjoy it very, very much and am glad I have it.
