Not to sound like I am knocking your lure, because I am not, I am impressed, and I am sure the right color in the right conditions, it would work very well. Part of why I am so sure is until a stupidity caused accident left a tackle box of mine in deeper water than I was near able to retrieve it from, I had some of my father's tackle with mine, mostly made up of lures from as early/old as maybe the mid 30's, but most were more like 40's to late 50's, maybe a little early 60's.
Anyway, there were two that were basically low tech, old fashioned looking rather than star trekie looking versions of the very same thing, and they worked well. I am sure that one was a South Bend, though possibly both were. All were in their original boxes but it's been enough years now that I do know the box colors were very different, I can't begin to make out a name for the second.
Anyway, a tried and true very old basic design that looks like it's been well refined. I like it.
