Tried all of the Canadian Clubs and since the best of them, which is the 15yo and the rest of 'em are only fodder for mix, usually coke, makes it a waste to buy anything but the cheep stuff.
You have to keep in mind that most Canadian ryes are blended to have some extra bite to accomodate mixers.
With Canadian Club there is not much difference between the standard and the 15yo, it's all swill or bar-rye quality.
Gibson's silver label is smoother than the CC 15!
I met a girl in Vegas that just couln't get enough of my Canadian club, but that's another story.
