Dacron is not Spiderwire. It is easier to tie and less stiff. 100# dacron fishing line is a good choice, but you're more likely to find it at store which sells fishing equipment to saltwater than to freshwater-only fishermen. I use spiderwire, but will probably switch to Dacron. I put my Ritter thin pencil in a drill chuck, spin it slowly, and spool up plenty on the pencil. Then hold it with an overwrap of electrical tape.
