I think it should be completely solid. It doesn't fit in with the design of the rest of the elements to have that faded center.
The center isn't faded, it's white. I don't think that's the problem though.
All right... This may sound a little blasphemous, but...
...I am going to...
...modify the Zanz trident a little.
*GASP!*
Wait, wait, it's okay. Don't sic your lawyers on me. I'm just going to make the fuzzy edge a little more solid. Adding a glow onto a fuzzy edge makes it look weird and doesn't blend well.
