 Brent,
 I've read that if you run too cold a plug, that it can overheat, and cause detonation/run on.
 Does this make sense?

 No problem at all. If I may piggyback on that...if you're going to switch up here on your plug, can I assume you maybe want to shade them a little hotter rather than colder and then check them as well as keeping an eye on temps. run-on, etc?
