Just a follow-up to say that the regular Crown Royal can't be beat for expressing the essence of the Canadian style, at a fair price. Just the regular version is fine although the Special Reserve version is good too (it has a little more taste, seemingly of older whiskies).
Sometimes the regular expression of something expresses its character the best.
It is good to see though experimentation with extensions such as Cask No. 16, since it widens choice and offers the possibility to create a new standard.
It would be nice to try a CR finished in a barrel that had held a well-aged, rich sweet bourbon or straight rye. Or do that plus add more bourbon and rye to the base than it now contains.
Some time ago I added a splash of Beam Black to regular CR and found it excellent. The drink was richer and deeper but still Canadian in style.
