our team has only used 35 chain. we have absolutely put it to the test too, and it has never broken. our bot in 2006 outpushed every ither bot we went up against, even the ones with outback style track designs. we bent our frame causing the chain to rub the inner frame rail, the wheel, be out of alignment, and have excess slack. it never failed. we had to replace our wheel cuz the chain started to eat throuth the aluminum side plate. 35 chain is cheap insurance. use it!
