and for the teams that used #25 chain did you ever have problems with it slipping under pressure? or possibly even breaking?

Yes my team last year had problems all the time with it slipping but it also broke on us alot we had used both #25 and #35 chains

This year our prototype base ran one loop of #35 chain. It needed to be #35 to handle this higher stress, but the overal weight saved in sprockets and chain made it lighter than running #25 with double sprockets (chain from trans to back wheel, chain from trans to middle wheel, chain from middle wheel to front wheel).
