I'm down to just 1 at the minute which serves both presentation's I favour, 7-8 inches of ESP Tungsten Loaded, strong wide gape hook (at the minute this ESP Croygen Grippa not used them long enough to make a proper evaluation), piece of tubing over the eye, hook ring swivel and hook bead, I just adjust the hook bead and putty to weather i am using a pop up or wafter.
Looks like most of the good reliable rigs are already covered in other posts
