If you fall down.. Did your mom ever tell you to never run with fork in your mouth? As long as you're not running with Canadian I don't see any con.
I don't think Altinay designates a specific model that they reproduce. They just occasionally have Canadians on their site. I'm sure they could make one for you if they don't have any currently on display. @Said.ALTINAY is frequently here on the forum.
Altinay usually has a number of shapes and styles that you don't normally see elsewhere. Canadian meers seem to be kind of rare for some reason.
Is this a Castello 33?I think it is a myth that a long shank does contribute to a noticeable cooler smoke. But I could imagine that it does have some advantages considering moisture, since there is more space for the moisture to spread instead of collecting at one spot, which may lead to the infamous gurgling. But all this is speculation and maybe more important: The Canadian is a great looking, classic shape.
