After some research and a few nudges (thank you HardcoreB!) towards using the 18725643 firing order on my next 511. I was thinking that perhaps I am not the only guy thinking about this upgrade (if it really is one) and that maybe we could get a deal on say 10 cores. If there is interest I will pursue the matter further.

Please feel free to disseminate any info you have on firing order swaps. At the "going rate" it is "only" $550 more, or about 2x the price of a custom solid roller. I was kind of against it based on sticker shock but then the little racer buddy on my shoulder reminded me of the other items that cost 2x parts that would have worked "just fine".

My reasoning for trying this is to reduce crank flex and to better distribute the load across the bearings.

Thanks for looking!
