You can also make up a teaser type rig with these on 30lb mono. Tie a palomar knot on a
swivel, leaving like a 20" tag end. Leave enough main line to tie a 3/8" head to the longer end leaving about 30" from swivel to head. Tie a smaller head of the same type to the tag end leaving about 12" from swivel to head. The heavier weight in the back reduces the helicopter effect when casting. Crush the barbs and land some doubles. Apologies if you knew this already.
