Topband: K9AY Loop Question

[N4ZR]

I'm in the process of putting up a K9AY loop, using the Array 
Solutions/Wolf RF control boxes.  I had the antenna up last year but it 
didn't seem to work very well, and I'm looking for suggestions.  A 
couple of areas for which I've found no answers:

How important is the geometry of the loops?  Illustrations I've seen 
seem to imply that the lower legs should slope upward somewhat to the 
corners, but without dimensions other than the total length of the loops.

The ground around the antenna slopes slightly toward one side - should I 
attempt to get the corners in the same plane, or the same distance above 
ground?

The relay box is mounted on the central fiberglass pole is approximately 
2 feet above ground.  Is this dimension important?  The relay box is 
grounded to a ground rod very close by.  Last year I experimented with 
also laying a couple of radials on the ground under the loops.  I read 
that suggested somewhere, but don't know if it's a good or bad idea.
