I usualy fish with the folowing trace,30cm sinker line tied to a grapnel sinker(weadeater) at one end and the swivel at the other,hookline is just a bit shorter so that i can clip it if need be.i tie my mainline to the swivel on the hookline.now the problem is and ithappens more often than not that my hookline's tangled up with my sinker when i reel in the line.How can i prevent this form happening or must i stop using these sinkers?does this happen when i reel in or when the sinker rolls around in while in the water?thanks
