Just in case I am missing something, what is the offsetting benefit of using #25 if there was so much stretching and retensioning required etc. Is it primarily weight savings (with sprocket weight savings) ?

While I can't recall exactly where I read it, I remember seeing somewhere that #35 chain is about 2.5 times the weight of #25, so the weight difference is significant. For the small amount of time it takes up front to line up the chains properly, and re-tension them a couple times throughout the season, the weight you save is definitely worth it. It also looks fantastic and is much nicer to work with, but those aren't exactly competitive advantages.

I highly recommend using multiple small plastic spacers if you join the #25 side. Makes lining up the sprockets a breeze.
