If a large morning tide occurs mainly before daylight, there is a higher incidence of Prawns in their guts. Prawns are primarily nocturnal. Although the YFW can access them buried in the sand where they hide during daylight hours and are occasionally disturbed out of hiding. Often by Stingrays. So it is not uncommon to see YFW close to feeding Stingrays.
I have only caught one YFW on a Cranka Crab lure. I think I have to use them in the Crab habitat and not on the flats.
The Sugapen 95 in Col-MB16 I feel mimics the prawns best. The Ecogear ZX43 blade mimics a disturbed fleeing prawn
