I surely can be accused many a time of having analysis paralysis, but I'll take over-analysis any time over not thinking it through.
We have been asking so many people, builders, drivers, crew members, bla bla bla and it's pretty much been bronze and a few supporters for a composite with mixed results.
Yeah that gear guide is the text from the link I posted a page or 2 back. That made me feel a lot better I guess.
Bottom line is we now have 1 of each of the 2 gears that are made to be run with my cam. And we will be checking the oil and gear wear here often in the near future to make sure all is well.
I do appreciate everyone's comments and advice -- these discussions are far more rewarding than all the pictures and videos -- esp when they help prevent making the mistakes others have made and avoid future carnage.
