anyone try NGK Iridium IX plugs

I still have the original plugs with 27,000 miles in our 950 vstar (unless the dealer changed them at 3377 miles prior to us taking purchasing). According to NGK's website, I would use Iridium IX : CPR7EAIX-9. Has anyone tried these?

I prefer a more frequent change of standard plugs. Lets me see what's going on, and you get the new newness. Copper is a better conductor than the Iridium, they just have a much longer change interval.
