Glad you bought something wider than a 35. My 17-40 is my most used lens while traveling and when I had the 24-105 I hated not having 17mm but seldom used 105mm.
I now travel with a Fuji setup for my "casual" photography trips which is a 14mm F2.8 and 35mm F1.4. Awesome tiny setup (mind that this camera is a 1.5x crop).
