When using running rigs what hooklength would be more suitable? If i was to use braid i would use 6" of sufix heavy skin, esp raptor size 7 and shrink tube. If i was to use mono i would use 8" of it and a esp stiff rigger with a braid hair. In your opinion what offers the best hooking potential? I think that the stiff mono combined with a running rig means hardly any chance for the hook to turn. Any advice would be much appreciated, thanks
