Finesse is a lure quality along with presentation that gets it done especially when fish are inactive after a front.
I pour plastics using injection molds or use a candle flame to come up with new shapes and actions fish can't ignore.
Finesse does result in numbers but also many quality fish of each species. I wouldn't go fishing without them.
The bulb-tail produces a waddle that, like all the other designs shown, tickle the senses of fish making them attack.

These also move the same way and are proven fish catchers:


These different tails produce a nice up-and-down flicker action:

The lure on the left has a craw claw attached to a Sassy Shad body; the forked fin-tail on the right is attached to a French Fry stick segment.
Close up of the claw:


Spike tail grubs are the ultimate in getting fish to attack when the bite is really tough.


The one on the bottom is the joining of two Bass Assassin grubs and wacky rigged.


Here, a French Fry segment is attached to a curl tail. The texture of the body may add to the lure's success.



...and another was joined to a thin flat tail:


A Sassy Shad tail was added to the FF:

Good job!

Wonder why the photos aren't showing.

Good now.
Anyone can make hybrid modified lures with a candle to slightly melt the ends, a steady hand and an eye for making the parts fit.
