Danderson, It is my understanding that CD's and DVD's are made from almost pure polycarbonate crystals. I too thought they would be very strong. I made several crank bills out of cd's and dvd's spent a lot of time on them cuttint shaping and scraping off the aluminum coating so they would be clear. first one I took to the lake lasted about three casts and it hung up in the rocks. while trying to pull it free, It came loose but the bill was shattered. same thing happened to the next one so I wouldn't waste my time on it if I were you.
