After paying I believe almost $5 a piece at the marina I was moored at and losing 2 in one morning trip I decided to see if I could cut down on costs. I purchased the lead blanks on Ebay and already had the hooks and swivels. My setup is far less sophisticated than yours. Just a rattle can of Rustoleum hammered copper penny and a piece of cardboard. Hopefully they last a few casts before peeling off.
Clearly I agree with Crunchy on the success of rootbeer.
Tight lines and screaming drags!
