All my elements are mounted above the boom except on my FS 40m home brew
where 4 heavy duty 60mm Stauff clamps are used with each element.
Its easier to use a spirit level on top of the mounting plates when you work
alone.

##  Nobody mounts els on top of the round booms, they all mount below.
Since the els sag at their tips, I see no advantage to mounting els  below
the round or square boom.  With eles  mounted below a boom,   you now have
the entire weight of the ele, plus any ice loading, sitting on the mounting
bolts,
like those used on stauff clamp assy..which are only the .25 - 20 variety. 
If els mounted on top, you have zero weight on the bolts, or u bolts.  
Thats not that big a deal, except for maybe 40m eles, in
which case you would have at least 2 x ss  u bolts on each side..or a min of
2 x
stauff clamps per side.
