Hey Jeff,
I am new on the forum as well, and have just recently started venturing in the world of single malt whisky. The glass that I have preferred using lately is "The Official Canadian Whisky Glass" . From what I can tell it seem to be a cross between a the traditional Glencarin Whisky Glass and a small tumbler (see image below). It has the flat bottom and width of a small tumbler style class with the same "tulip" shape of the Glencarin.
