Not to nit pick and not to confuse anyone but the "Galloway" cast referred to is a "Galway" cast. Galway is in Ireland, noted by it's local for windy conditions. The Galway cast has been around for a long time. I'm not going to explain the cast, you can google it.
My response to the OP by Ole....quote: "I've watched several videos on the voo doo cast. Other than looking rather cool, is there any reason to use this cast if one has plenty of back cast room?".......IMO...No.
