I've made a lot of a rigs and have used the premade harnesses also but I prefer 325 lb or225 lb stainless wire that you can order from all the usual places I believe the 325lb wire is.041 but it's been awhile . When you use this wire you are not limited on the mold you use you can just about make it fit any mold . I use my spinnerbait mold or the do it a rig mold and I also have the boss mold but I do prefer boss harnesses for their molds although you can also use the wire for their molds also
