Outstanding Bob !!!!!!! Excellent !!!!
Tip: the same lures you make and use for this design can be modified for body and stinger tail sizes.
Cut the thicker parts to be joined to shorten the body or
Cut the tails shorter and reattach to the body.
Both sizes you made will most definitely catch fish !!
Now it's time to fill a pail or the sink with water and see the action on the drop or twitched mid depth. You'll probably want to break the ice and try them out in your local lake! Be my guest if you want to sell this design and spread the pleasure to fellow anglers. You're in the business, I'm not and you can offer a range of nice colors and sizes. I've caught
6 species of fish on them.
Tip: next thing to try are the mini-sticks : 2 joined bodies minus tail/ diameter around 1/4".



Man do they catch fish with their walk-the-dog wag darting action !! Will also catch fish wacky rigged (see above) and like you showed.
