There is some 30lb braid included in every pack.
Bry, The trap relies on two round surfaces being held together under pressure from the spring. Similar to the two pieces of wood that butt together to hold a Larsen Trap open. If you put a groove in the trap then the trigger will not dislodge as easily. There is only a slight issue when the traps (and trapper) are brand new. After a day or so you'll both get on better.
