Our leads and wings are hung like seines with #15 nylon netting on a "150 per 100" basis.
Single top and bottom lines of 5/16" braided polypropylene are used.
A sponge float is placed every 30" to 36" (at nearest tie) and a lead sinker is placed every 10" to 16" (at nearest tie).
All leads and wings are 6 ft. deep.
