im using an a20s shock mount, with two sg20 stand clamps, and a homemade spacer (some 20mm pvc rod, drilled and tapped with 3/8 studs in each end.)
I have some different length spacers, so overall you get the low profile of the ortf bar, with the adjustability of the vark bar.
considering i usually run fob, i rarely stick to established patterns like ortf. and this is a very very low profile setup.
I've got a 5' length of pvc if somebody wants a piece
