Nope... not me... Not nearly enough contact for my tastes...
I want a TRUE galvanized or stainless clamp that was tailored as closely
to the leg diameter as I could get and AT LEAST as wide as the strap I
am using... Like 2" or better wide... Think wide turbocharger clamps...
Then I want either a properly wound intermediate copper shim that is
fully tinned on one side and bright copper on the other, OR a properly
formed copper strap which is fully tinned on the contact side.
Copper strap... as wide as I an afford and get formed to fit the leg,
preferably with nice smooth transitions.
Then I want a suitably compatible conductive filler paste to exclude any
moisture form minute gaps anywhere in the clamp system.... preferably
where the carrier durable enough not to wash out. (I used to make stuff
like this).

This kind of design, but say 3 times wider.... 3 fasteners.... Or
simply stack 3 high.
Whatever you can do to reduce resistance/heating/inductance/corrosion at
the junction.
