i was thinking about making me a drag for trolling in the wind. i been using a 15lbs kettle bell but even with it being perfectly round after a distance it will cake up with mud and stop me. (h18 express with 115). my plan was to have 5 lengths of chain cut and hook them all together with a caribiner that way i can take off or add wt based on the wind speed. my question is what size chain. 25' of 1/4 weighs about 23lbs. 25' of 1/2 is over 40. any suggestions????
