Those lures WILL work for big bass,might work well for barble,tigerfish too.
While i fished for tigers at a private dam,outside pongola a little green snake dared to swim across to the other side,as he swam they ambushed him,and i assume they killed it cause i didnt see it after the fish pulled it down unda!
And a buddy of mine was fishing at a small dam for bass,all of a sudden he heard a huge splash,and saw a big bass breaking the water with something in its mouth,he casted there right after that and got the fish,he wanted to lipland the +/- 2,5kg fish and when he grabbed the fishes lip the snake was still in its mouth,all of you know what happened next(a loud yell,water splashing,reeds breaking)
He didnt land it and took out his knife and sent the fish on its way!those lure should do a good job!!MANN's lures company also have a snake lure,floating too!!!
