All the fancy spark plugs out there are just that....gimmicks.
The spark only jumps in one location, the path of least resistance. Having 2, 3, 4 electrodes does not mean there will be multiple sparks. The reason for this is longer life and better resistance to fouling, which is why the platinum or iridium OEM plugs in cars often carry a 100k mile service interval.
The p/o had put iridium NGK's in my bike, when I pulled them to look the ground strap on one appears to have melted and "splashed" onto the porcelain. I replaced them with stock NGKs and that was like 20k miles ago.
