Whether store bought or poured soft plastic lures, there are unique designs just a little imagination can create using a candle flame and the parts of two lures. Most move differently in the water and catch different fish species plus you can downsize or increase a lure's size. I hand pour or inject many of my lures and still find uses for the parts of each I can melt together to change body or tail shape and action. What has surprised me was how it seems the new
hybrid lures caught fish better than the originals. Here are some examples:
hybrids or just parts cut off of a Sweet Beaver:

Note the claw from the Beaver added to a grub body (above) caught this and a bunch more panfish:

One of my best discoveries: fuse the bodies of two grubs after removing the curl tails:



Wacky rig a light jig or rig the usual way and FISH ON!
Claw of a craw lure added to a grub body:

Two tails from an injection grub mold added to a worm segment/ wacky rigged:


Kut Tail Worm tail added to a thicker grub body:


Even small sunfish jump on it:

Added a tail spike to a grub body:

Here I added the head of a craw lure to a grub body:

Most of us have over 1000 soft plastic lures hanging around unused and the means to pour more. This has turned into a subhobby of lurecraft and I highly recommend it. The ideas presented
all catch fish when rigged on a light jighead and there are many others I haven't posted. Fish sense lure shape, size, water displacement and action even at night and strike these like no tomorrow.
