I use the Glencairns for critical tastings, but I love the feel/weight of my Crown Royal Black square tumblers. If I'm just drinking, the tumblers are always considered, though not always chosen. They came in a gift set, and I gifted the Crown, kept the glasses. One of the reasons I like them is that crescent shaped ice does NOT mimic the contour of the glass. Movement of liquid to my mouth is therefore NOT impaired. Ya gotta have priorities, right?
