Imo, the radiating glowy spikes just don't seem right. I was thinking basically a TMP-Enterprise-style glowing deflector, but smack dab in the middle of the dish, about half the diameter I would say. "Gridding" it would be the copper lines of the dish. That way you have more or less a direct hybrid of the TOS and TMP style defelctors.
Either that, or add a glowing ring with a radius of 1/2 the dish, and add a small glowing center, like the Galaxy-class deflector.
