Hi,I'd like some advice on the size of pendant light for my dining room table. I'm looking at either the medium (diameter of 19", height 15.5) or large size (diameter 26.75", height 23") Nelson Bubble Ball (http://www.gabrielross.com/lighting-20/bubble-lamps-206/modernica-bubble-lamp-suspension-ball-677.html). We have a surfboard style table about 37" in width. It's a saltbox style home so the ceiling slopes from two stories to one over the table. It would be hung at about 1.5 stories. I love the look of a large ball pendant, but I don't want to overdue it. I have no local retailers to see one in person. Any suggestions?thanks in advance.
