swore i was going to go with the 135L as my only telephoto, but now i'm starting to worry about versatility if it's going to be my only telephoto lens.
tell me about how shoddy the IQ of the 70-200 is so i can save $300
All of the Canon 70-200mm L zooms produce excellent image quality. The real question might be whether there would be more value for your shooting in getting the f/4 IS version rather than the f/2.8 non-IS version.
I shoot the IS f/4 version frequently - in fact, it might be my most used lens. I also have the 135mm f/2, which is a fine lens, but useful for me in far fewer situations. However, the combination of the f/4 zoom (for excellent image quality, flexibility, reasonable weight/bulk for such a zoom) and the f/2 prime (for certain types of low light and for very narrow DOF) is more useful to me than owning the f/2.8 zoom.
