Re: chains

#25 ANSI chain has a working load of 140lbs
#35 ANSI chain is 480lbs
then next after that is #40 at 810lbs

So you get a significant increase in strength going from #25 to #35
I think it's possible with some FIRST bot setups to take #25 past yield
or at least well into the built in safety factor whatever that may be

But I can't see harming the #35 with a strong drive train under some
shock loads.

I think #40 is just overkill and too much weight.

FIRST provided #35 chain in our kit last year, I think it was 20'.
along with some #35 sprockets. So it's not a bad idea to stick with
#35 just in case you want to use them.
