IGFA ruling on A-rigs...

"After significant review by our Rules Committee, we consider your lure to be a spreader bar arrangement. IGFA Equipment Regulations state: "spreader bars are permitted to be used provided that the actual fishing line is attached to the snap or other release device, either directly or with some other material." Since the angler's line is not attached to a release device so that the hook could be disengaged from the lure arrangement, this lure violated IGFA equipment rules for spreader bars."
