Interesting question...
I think more often than not they would catch the same fish. Most fish the skinny carrots wacky, on a shaky head, Texas Rigged, split shot or drop shot.
From an action perspective I would watch the videos.
For me to compare it to a trick worm I would want to make it a little thinner. I don't know how important the fatter tail is. On a trick worm it is important, but the Carrot would get it's action from having a thinner tail. - Tricky Carrot?
I'll be curious to see what others think... It would definitely be worth testing.
