I was experimenting with different toploads about a year ago, and once I 
put a smaller toroid on top of a larger one. (Both 110 mm minor dia., 430 
and 540 mm major) The streamers were still breaking out from the larger 
one, but downwards, at an angle of ~30 deg. below the horizontal plane of 
the toroid.
Increasing risk for primary strikes of course, but something that may be 
interesting for us with a low ceiling...
