Depends on how much you're willing to carry... I'd probably take all of it.
On a trip to China last year, I brought your list (essentially - 16-35 II instead of 17-40, 70-200 II instead of MkI), and a TS-E 24mm II, 1.4x TC, and 430EX II, plus an S95 for times when taking a dSLR wouldn't be possible. I used the 24-105mm the most, followed by the 70-200 II then the 35L. Although I didn't use the UWA zoom or the TS-E that frequently, the shots I got with them would not have been possible with other lenses.
For me, the key was the right way to carry all of that. The gear all fit in a Lowepro Flipside 400AW, which I then packed into a Pelican Storm im2500 for the air travel (in case forced to check, also for a lockable case for the hotel room). I packed a Lowepro Toploader Pro 65AW and a Lens Case 1W into the main luggage so I had an easy way to carry camera+lens and one extra lens on day outings.
