I'm trying to decide between buying Riedel Vivant glasses (exclusively at Target) or the Ouverture glasses? Both are their entry level lines, but from Google images the Ouverture glasses look a bit more stubby. They're typically similar priced ($10/glass) but Williams Sonoma has an amazing sale - http://www.williams-sonoma.com/produc... - with 12 ouverture glasses for $80. Trying to decide between getting this or sticking with the Vivant glasses which I have bought in the past. Thanks!
