Actually, the original RR heads and the Pro Series heads have light wire that is specially tempered to straigten when hung up. You can rebend the hook up to 11 times and keep fishing. We're testing constantly testing other hooks but haven't found anything better, yet. Oh, the Pro-Series heads in the 1/16th have a number 2 hook instead of the smaller 4. (My favorite head BTW) I hope I answered your question completely but let me know if not. Blessings, -TJ
