I cut up the downtube bottle last night. I did a horizontal cut, right about where it starts tapering towards the mouth piece. You can stash 2 tubes, a lever, CO2, inflator (I have the shiny objects one...super small) without it bulging out too much. Since the walls of that bottle are quite thin, any packing in will cause a little deformation. I taped the top back on with some 1" gorilla tape and it looks good to go.

I stashed another CO2 in the tritone 'behind the saddle' bottle mount. There's alittle threaded hole. This way, I have 2 tubes (one set up for the disc (40mm stem) and one for the 60 front (80 mm)) and enough gas to inflate them both. I guess I could change the 80 mm stemmed tube to a 40+40 extension and jam a spare 40 mm extension with the lever. That way I could either flat the same tire twice or one of each before getting into trouble.

For Victoria, that'll give me the big front bottle for drinking and a bottle behind the saddle to fill it back up. Flat kit on the downtube. Gels in the bento.



(Tinypic was being troublesome. If the pics above don't load, I'll try again later.)



...and BTW, when I tested in the tunnel, I was faster with the downtube bottle than without it.
