This decision is driving me nuts and my wife is about ready to kick me out of the house I think because of my constant waffling.
I currently have the Canon 17-85IS as my everyday lens. It might be hard to believe, but I really like the lens a lot and it has rarely let me down. However, my main subject matter is my daughter and she is now going on five years old and I often find myself at 85mm and wish I had just a little more reach. I could zoom in with my feet but generally I have missed the chance to get the picture by then. I rarely shoot at 17mm these days. I generally use a flash indoors as it is, so the f/2.8 isn't a huge deal unless I am away somewhere and I generally don't keep the flash on camera if I can help it.
I already have the 55-250 which works great if I know ahead of time that I need it, but when we go away for a day I usually prefer to pack my camera (30D) and one lens. This has led me to the 24-105L. I know I am supposed to want the 17-55 but I hate the focal range despite the fantastic optics. I refuse to consider a lens without IS.
Am I crazy so wanting to upgrade to the 24-105? Is there is better option that I am not seeing?

) So, I also like the build and weather resistance of the L - I do a lot of hiking in the Mtns. of NC where sudden storms are common - I would love to have a camera that I know could withstand frequent showers
