Ozark,
Care to share what it is and what the improvement is? There is a good chance that there may be some on hera that would be your first customers! Is this a species specific type bait i.e designed to catch bass or walleye? Is it a surface, subsurface, deep diving? Crankbait, spinner bait, spoon,....
Details man, details.... Congrats on the design improvement. If you'd prefer to PM the info, I'd be interested in hearing about it.
