17-40 L or 24-105L for landscapes

We we in Italy in September for 15 days.  Had 17-40, 24-70 and 50 Zeiss with me.  Used the 50 for some panos, some with the 17-40 (one of my favorite lenses) and the 24-70 stayed on the camera probably 95% of the time.  I have the version I and it was perfect for Italy.  Only complaint is it gets very heavy carrying it around.  I used a Black Rapid strap most of the time which helped with the weight and getting it off my chest and neck.  I still use the 17-40 for a lot of landscapes and panos.  It was my go to lens for about 3 years.  Have fun in Italy, it is a wonderful country.  Best,  Bob
