#25 can work, but #35 much more forgiving...

I know that #25 can work. We used in many many years with no problems that we didn't cause ourselves.

But... we had to spend a lot of time thinking about how to make the chain work right for us. We put designed in robust tension systems. We paid close attention to alignment of sprockets. Etc.

Last year, we went to #35 chain because frankly, we were not confident that we had the ability to make it work for us given our level of resources last year.

Based on what I saw, in the future, I will use #35 chain in almost every case over #25.

#35 chain is SO much easier to work with. From alignement, to tension, to abusive loads, #35 will let you get away with many more sins before it damns you to hell.

So... ...that is where I come down at least.
