And don't misunderstand me, I think Dave has sweated out the details and come up with the best jig head for Ned fishing that I have ever used, BUT I don't just carry one jig head for Ned fishing. I think I am using two different non weedless designs (one has a collar and one does not) and then the head that Dave came up with. I have also used the Skinny Bear heads that you can get from TW, at Dave's suggestion, and they work very well, but cost more and rust QUICKLY if the chunk is left on the jighead at the end of the day. I had hook failures from this type rust on fish which is not acceptable so be forewarned on that deal. I'm done with Skinny Bear, but they work too.
I saw the Z man Shroom jighead in person yesterday. I saw it catch fish and it can be used without glue for a little while. I would still glue mine from the get go, but that's just me. The hook seems roughly the right size with VERY thin wire. I don't think the hook Dave uses will ever let you down on a bass, but I would be shocked if the Z man head can hold up over time. I strongly suspect it will lose its temper and bend out or snap. Expensive for my tastes as well, but they will work.
