pick your poison...

Both have pros and cons.

We have always gotten by with #25 chain but this year we have switched to #35 (though we have not used chain for our drive system since our rookie year).

The reason is basically, we are worried about skipping chain with vigorous interaction expected. It is overkill we know, but we have seen so many teams lose matches because they have thrown a chain that we decided it was an overdesign we were willing to live with.

Bottom line, #25 can work well if you can keep the chain tight, the sprockets in line, and competitors from poking your chain from the side. Even if you can do all these things, you will sleep better at night if you use #35 chain.
