Last year we did fairly well in the Derby. ( 1st and 3rd, cough, cough)
We ran the same 4 flashers the whole weekend.
One purple haze
One blue
One purple (old)
One white (commercial guy said they used to use white)
What does that mean exactly, I'm not sure, I think it means the colour of the flasher has very little to do with successful chum fishing.
Others more experienced in chum fishing may be able to offer better advice. Blue Orca, Paul, are you out there?????
He's a master in my books.
