Spark Plugs for 2003 VTX-1800C

I have a 2003 VTX-1800C. I saw the thread in 2007 for spark plugs. I was wondering if anyone has more information about which plugs to use.

OEM were always the best in every test fellow VTX riders did. They last 100,000 miles and produced the best power

The 1800 NGK Iridium spark plugs comes in two flavors with prices to match.
The OEM 1800 spark plug is Iridium center electrode and a Platinum button on the Ground electrode(100k miles).

The 50k miles NGK Iridium spark plug at lower cost has a standard nickel Ground electrode.

I bought into the 'other plugs' hype before switching back from Bosch 4419 back to the NGK stockers. I gave the Bosch a full season workout, and didn't see ANY difference in performance or mileage over the NGK's.
