Okay, thanks for all the helpful input.
I do like the reach the 28-135 gives me, so I think they 18-135 is my best bet but I am still certainly considering a smaller wide angle zoom.
I usually shoot in daylight and well lot areas so the usm and quicker focusing isn't really a big deal to me I'm mainly looking for the conveinence of the wide angle and zoom all in one.
Anyone intersted in a mint 28-135 with hood? Haha
