There is no magic knot that gives the swimbait better action. You can tie it right on or use a snap swivel. Also you don't need a 9" stoolie, the 6" ones that come in a 3-pack at dicks work just fine.Hello everybody, at the end of last season this oriental lady showed me the stoolie/scap teqnique with a live herring. This offseason I got my own scap and rubber stoolie. Wondering If anybody can shed light on how to tie to your line to get that nice tail whip action. I don't want to rig with a hook nor do I want to risk losing it because they were hard to find. I found a nice silver 9 inch rubber one. Please let me know. The Good luck to all this season!
