Thank you very much, Buenchico, for the trouble you've gone to in order to answer my question. The photography was superb as far as I am concerned.
I'm not particularly fond of the rather 'squat' shape of some of the glasses, but I am convinced that the 'teardrop' shape, height and volume are just what we're looking for. Our order will be on its way ere the day be out!
Again, my thanks.
