I recently picked up a pack of the 10.5 inch yum mighty worms, but I haven’t tried them out yet. Does anyone have any experience with these?

I've never used big Yum  worms but  use big worms . 

I use them a lot on a carilina rig. They work and are cheap enough to replace

I use a weighted jig head with a worm rattle on my 10” & 12” worms.

I pour a swing head specifically for them. It's a 7/0 monster worm hook on a 1/8 or 1/4oz head. I use it for bouncing through snaggy rocks. I've also had good luck fishing them weightless around docks and over grass.
