If i know blues are the main event I use crimped wire. Otherwise snelled is how I tie them. I have also used a uni-knot and don’t recall issues with blues biting them off. I mostly use mono when stripers are the quarry. Biggest issue with blues is they can sometimes swallow the bait leaving the leader exposed to teeth. Have had blues bite through wire to but usually they just shred the leader after a couple fish.
Do u just crimp the wire with a single loop through the eyes of the hook so it swings free? Or pass through the eye twice so the hook is cocked forward?
