Try chucking a 1/3 oz. Little Cleo spoon. Silver/chartruese & use a Sampo Swivel.
Cast it out & count it down til it hits bottom. Then reel it back medium slow.
Fish are near bottom.
No offense but i wouldn't chance heating it..all you need is a good steady pull at each end to stretch the line out.
If it still has "memory" coils then use the leather or rubber tab..SLOWLY. Cheers,Dan'l
