Sideshow Bob,
we always 'toboganned ' whenever we took on fuel for real even from another C130. I am interested to hear you say that the Tristar is cleared to refuel the Herc. I seem to recall (C 130K) that when it was trialled the props did not appreciate the secondhand air they encountered from the Tristar. Perhaps the props on the 'J' are not so fussy. But it seems so long ago I may not have recollected this exactly.
