The multi-strand wire in the hook setups for skirted lures is more to save the 'expensive' lure from bite offs from toothy creatures, I have never experienced or seen a lite tackle Billfish [25-80kg Marlin] wear through 80 -130lb FC or 100-150lb mono, or heavy tackle Marlin [200kg+] using 300-400lb mono leaders through fighting the fish, even deep hooked ones fought over 2-4 hours.
Maybe it's a case of the lure not being through wired as I have seen the same system used on big Minnows.
