Alright...thanks for the feedback everyone!

I'm still on the fence regarding this.

It would seem that the Ruthenium HX w/ exposed thin wire grounded electrode design offers a potential improvement to the flame-front travel. I cannot imagine that this would be a bad thing in any application either.

My ignition system today is a tranditional MP Chrome ECU + Yellow Coil combo, plenty of hot spark on my current NGKs which are gapped at 0.045". Although, I do have the MP (part# P4876729) labeled MSD box, which I believe is the 6ALN actually, that I was thinking of trying out springtime.

Anyways, I am thinking that whatever difference these make, may not actualy be noticable given my application, that being the regular "weekend warrior" type of a ride.
