"I tried out the 10-22 and i like it i just have this thought in my head that its going to be to wide, for my type of shooting... I have never tried out the 17-40 but it looks like a focal length i would like..."
I use the 12-24mm Tokina f/4 as my wide lens. I like this lens because of the quality of imagery, build and of course price. It is considerably less expensive than the 120-22mm Canon - about 2/3 the price when you consider that the lens hood is provided free of charge with the Tokina and you have to buy one with the Canon.
I don't like the 17-40mm f/4L lens on a 1.6x camera. It is simply not long enough. I tried to use it in conjunction with the 70-200mm f/4L but the 40-70mm gap drove me crazy. I do a lot of shooting in that area.
The 17-40mm f/4L is a very nice wide lens on a full-frame format. It comes very close to the 12-24mm on a 1.6x camera. IMO, the 17-40L is a fine enough wide angle but, is not an all around lens for a 1.6x camera because it is to short at 40mm and is too slow at f/4.
The 12-24mm or the 10-22mm lenses would be an excellent combination with a 28-135mm f/3.5-5.6 lens but, I wish that the 28-135mm had a bit better image quality, newer IS and a constant f/2.8 aperture.
I would expect that the Sigma APO 50-150mm F2.8 II EX DC HSM Lens would be an excellent combination with the 12-24mm f/4 Tokina but, it would be nice if the 50-150mm had Sigma's equivalent of IS incorporated.
My favorite combination is a 17-55mm f/2.8 IS lens with a 70-200mm f/4L IS on two bodies. I use a 30D and a 40D. The 17mm is wide enough so I don't always need to carry a wider lens and the 55mm is a much more usable focal length than is 40mm. I don't mis the 55-70mm gap the way I missed the 40-70mm gap in focal lengths.
"Bottom line is would you upgrade from the 18-55 kit lens to the 17-40L, or would you upgrade to a entirely diff focal length.I think the 10-22 and 28-135 will make a fine couple.Or i was thinking about the 17-40 and 70-200."
If you could afford it, the 17-55mm f/2.8 IS is a stellar lens. At a lesser price, I like the 17-50mm f/2.8 Tamron which has great IQ, good focus capability and is 1/2 the price of the 17-55mm IS lens. The Tamron doesn't have IS but, IMO, IS is simply icing on the cake in a lens of this focal length.
By the way engramarino's idea of 10-22mm, 24-70mm and 70-200mm is a great idea but a bit on the heavy side. I used this combination (except I used the 12-24mm Tokina instead of the 10-22mm Canon WA lens) for a while until I got the 17-55mm allowing me to travel with 2 cameras and 2 lenses.
