This is what the manufacturer of Buzz Bombs had to say.

Hi Dave:- That was my Zzing-L Hook (pronounced zingle), which made for perfect single hook alignment behind BB or ZZ lures. I have redesigned the single hook alignment process by making a special single hook bumper, which is a short piece of black tubing, cut at 90 degrees one end (goes again the BB/ ZZ, ) whilst the other end is cut at a 45 degree angle, which goes agin the steelhead type hook, which is 45 degrees also- the two 45's contacting each other cause perfect single hook alignment. You might view this on my website dealers page buzzbombzzinger.com, if he still shows it. Cheers- Dug
