Man,... I'm glad I got this plug thing started. You guys all kick butt! Thanks for taking the time to really use your skills and figure this out for us.
I'm feeling better about trying another brand. I do think the recommendation of continuing to use the same plug, or what ever you settle on would be a smart thing. Its nice to know you could use the OS plug, as they are cheaper and more readily available. As for the .003 well I just shimmed my GRP up for 30% and that shim measurement is much much larger than the .003.

You guys ROCK!!
