All I would say is use the correct chain for the right purpose. We used #40 chain on our drive this year but we did something with our drive I haven't seen and was not sure if #35 chain was able to withstand the side-load that #40 can...I hope. Just check the specs and realize bigger is not always better.
Here is what we did with our #40 chain and do you really think #25 or #35 would work as good?
