I've always liked the Moxon performance features (broad bandwidth, great 
F/B, smaller turning radius), and even considered buying the OptiBeam 
OB2-40M for a while until I decided to stick with the lower cost and 
slightly narrower pattern of the standard OB2-40.  The Leeson design is 
also very interesting, particularly since the weight balance of the 
cross members might preclude the need for the outer trusses used on the 
OptiBeam version.  But Cebik's material on Moxons on his website 
indicate that the coupling between elements is quite critical, so I'm 
wondering how consistent that would be for the Leeson version in a wind 
where the elements wouldn't necessarily move together.  It seems like 
you'd almost want to run a fiberglass rod or something between the front 
and rear cross elements, trimming as necessary for whatever effect that 
had on the coupling.

In any case, I'd be interested to hear how they work.
