I dont understand why that is?
Surely a barbed hook should have more damage to a fishes mouth than spring loaded rig???
This element which apparently sets the hook nicely, would be better than damage that may be caused when the fish try to eject a standard rig?
I'll try it on 1 rod until I'm told I can't..
Ali appeared genuine about this bit of kit, from what I could tell. Don't know him from Adam, but from the underwater footage, it would appear to be a game changer imo.
