Jojo, Kenneth and all, thanks for the assistance, and especially thanks to Michael for finding a picture of the glass.
It may seem a trivial difference between the Speyside and Canadian glass, but I like the straight sides better and will continue to search for the Speysider, even though I'm a committed Islay guy.
Another great find however was the identification of the glass I mentioned, which is pictured on the cover of 'The World's Best Whiskies', by Dominic Roskrow, and they are made by Villeroy and Boch. Named the Scotch Whisky Single Malt glass, in two shapes, one for Islands and one for Highlands, I also found a picture of one in my hand, no less!
That picture should now be my new avatar, except it doesn't seem to be showing up.
This may be taken as heresy here, but when I first held a Glencairn I immediately wished for one with no base, and in the Villeroy & Boch, I found what I'd envisioned.
