One thing to watch out for with all chains (esp. the #25) is the masterlinks. Of the five or so chains that i have seen broken, four were because the masterlink had been improperly installed or had grown weak from being taken off and reused too many times.
We have used #35 chain for everything and have never had a problem. Last year our robots speed was around 2 fps with two small cims per side. Our frame was bent in all the smash 'em' up bang 'em' up stuff and rubbed our drive chains, but they held up like champs. We out-pushed everyone we met last year, at regionals and in Atlanta. When in doubt, go stronger. We will never use #25 chain. Why chance it?
