Replying to Need advice on next lens

Ok, so money isn't really the problem. I need to save for the lens no matter what. What would you guys recommend, a 24-105 or a 17-50 f/2.8?

I currently have:
the kit lens
11-16
50 f/1.8
and a 135 f/3.5

im looking to replace my kit lens, what do you guys think?
+k for help.
