Look, we're dealing with a rookie team here. This is why we are advocating a "failsafe" approach. If this were a veteran team, we'd go to a "riskier" solution.

Yeah, I am offering to teach this ROOKIE team how to properly use this system. It's only as simple as using CAD to design your chain runs, and CAD is supplied free to all teams (in any flavor you want, too...). I agree that it's safer for you to avoid giving advice that may result in a bit of failure, but at the same time, if you don't start reaching for the sky early, it takes longer to get there.

There's a HUGE reason I always advocate #25: acceleration. A lighter mass to get moving will accelerate faster, so the weight loss from a moving part results in a HUGE acceleration increase.

So here's an offer: if anyone has ANY questions about how to change over a system from the heavier #35 chain to the lighter #25, please feel free to ask me.
