Until I got my fancy pants imported nosing glass I used a small glass mixing bowl. One that would fit around both my nose and mouth. I could breath in through both nose and mouth at the same time. A pretty good technique. It just takes a lot of bourbon to do it. Then I would just taste the bourbon right out of the bowl. It worked. Your 'fish bowl/ wine glass' sounds very simular. Use whatever works for you, and don't second guess yourself.
