Hi Funchy
You are probably right mate, bloodworms will outfish yabbies , but my knees don't allow me to get down in the mud anymore and the bank won't lend me any money to purchase them since I gave up working, so I stick to pumping yabbies, have found a couple of nice silty sand banks to pump over the years and good thing is I don't sink in it and the yabbies are easy to pump, I have switched over to using circle hooks for whiting since I had a fish with mangajack , to many gut hooked smaller whiting on your standard No 4 hook, I also rig them differently on the circle hook so they have a lot more movement and the whiting absolutely smash them hooked this way, only issue is so do the grunter
