Do you need to use a chod rig? what type of lake bed will you be fishing over?
If you find your self using leadcore, google terry hearns video on you tube or on esp website!
if you go for the much safer option of using a synthetic leader you can use a piece of shrink tube where the bead sits, then slide bead onto shrink tube so that it will still pull free, but best advice would be to rethink your rig and go with a SAFE rig
