Ive been a jig guy for years, and when i started using the Ned "ive posted my catches and experiences" it was hard for me at first to let it settle to the bottom without me wanting to feel it fall. After i got over that mindset, the bites came more often.
As Dave said, it fishes vertical well, and the bluff fish like it just as well as the shallow fish. I switched colors Saturday to see if that mattered, like other lures, and after switching from a PB&J Zero to a Watermelon colored, we caught more fish between casts.
In order to get good at anything, you have to practice, practice, practice, and on this forum, theres no-one that seems to have done that more than Dave, so his experience on this bait, in my opinion, is above everyone elses.
The limited number of hours "maybe 30" that i have used it, ive tweaked it a half dozen times, from length of plastic, size of hook, size of head, color, water depth, line size, etc. in an attempt to be a better fisherman with the bait, as i do with almost anything in life. Thats part of my obsessive brain, trying to do the best i have with what i have.
