Is anyone else having problems with the large wheels breaking the chain? Some on the team want to switch to #35 chain, but that seems like overkill to me. I feel like we must be doing something wrong, not that the chain is too weak.
Thanks!

#25 chain is very sensitive to alignment, if one sprocket is 1/8" further out than the other, it'll bind up and have problems. Make sure you don't over-tension your chain, as this also makes it more likely to snap. There should be a little bit of slack in your chains, but not enough for the chain to be noticeably floppy. Especially with a game like this, #35 chain is definitely not overkill, and it's much less sensitive to alignment. We're using #25 for mechanisms, but #35 on the drivetrain is definitely a good option.
