   Thanks for the detailed explanation, but in this case the best
solution was the one the other Bill P. suggested. A merge of spheres
with same radius and placement did work pretty well, and in this case it
doesn't matter as it is an invisible container. It still does the job of
being a close container, and the speed up provided is even a little
better too.
