Ok, I bite and bought a set too since it was on sale.
I use a glencairn about 90% of the time, but I found these at Pier 1 for about $3 and they're awesome for an ice sphere:
I don't use mine every day, but when I want to add an ice ball, I tend to reach for these glasses.
Enoch, glad you like yours. (And since this post makes me sound like one, No I'm not a Sun's Tea salesperson).
