It would depend on where/when. For general purpose, I'd take the 24-70 and 70-200, but if I knew I'd need to shoot ultrawide (buildings, landscapes), I'd take the 16-35 and 70-200. If I'd be out at night, I'd take the 50/1.4 and maybe nothing else, or for day then night the 24-70 too.
My current 'small' travel kit is a gripped 5DII (soon to be 1D X) with the 28-300mm f/3.5-5.6L IS and 35mm f/1.4L.
