My experience with Tanglefree decoy cord is not good. It gets so stiff and brittle in cold weather it is a headache as it will break. My advice would be to get some heavy (atleast 3/16 tarred nylon line. I agree with the post that said nylon line is no good if it is very fine. It tends to tie itself into knots and is a booger to get out of the decoy bag without having them all tangled and tied together. The strap lead weights are the way to go if you are hunting relatively quiet water.
