I don't know what seal billy uses for a swivel, but I never use one on spinners�every 3rd or 4th cast I need to let out about 4 ft. of line and let the thing 'unwind' as it were, but I haven't found a swivel that will get me the quick starting speed I need on the spinner. ( The majority of my fishing is fishing upstream, retrieving with the current so getting the spin started can be problematic�)
