I wouldn't image the cross links are critical provided enough vertical circles are used to fool the e-field into thinking it is a perfect sphere. It is sad that the better the transparency is, the worse the field uniformity is. There is a point, however, where the field is virtually perfect and yet the grid is still relatively, ion transparent.
