Soft plastics will always be my main bait to catch fish simply because there are soooo many shapes and designs fish strike.
Last week I experimented with a few and caught 5 fish species. Here are a few that did well:

the curl tail of course but on different body shapes:


the claw:


Crappie Magnet tail added to different grub bodies:


Blunt tail:


These and other lure shapes caught fish on the same day in the same lake last week. Got more to try when the weather clears in the next few days.
