A copper tape was selected for winding, dimensions 0.3x34mm, two in parallel. The measured value is 10uH, there is no more place for more. Estimated saturation current is ~300A  and their saturation is not sharp but relatively soft. Made two such chokes, use in serial with toroid each leg. Used bits & core datasheet chK_core.pdf
