Nitrous Plugs

I've posted on a couple of forums but realy can't seem to get a solid answer.
I have installed a set of Dart heads which require a flat washer plug, and I am running nitrous, (although actually spaying very seldom.) What is a good replacement for my TR6's?
Some are saying the Denso Iridium plugs work great, but I have also heard that they should not be used with Nitrous...Thoughts??

I use the Denso Iridium with my 175 shot without any trouble. There is also a TR6 Iridium equivalent that my friend uses which he loves and is cheaper then the Denso. You DO NOT want to use Platinum plugs with nitrous, Iridium or copper is fine, and actually my idle improved with the Iridium over the TR6. I gap my Denso IT20 at .042 just to let you know.
