well. you seem like a prime kind of person, and already have the 135, so unless u really feel the need for a zoom, that probably takes the 70-200 out of the picture.
when you say 30D+200mm does that mean you would be getting a 2nd 30D? just clarrifying.
i guess it comes down to do you want/need more reach? or do you want the 1.2 bokeh for portaits. If you really want more reach i would suggest getting the 300 F4 IS instead. the 200 2.8 doesnt give THAT much more range over the 135. and if you do want just a bit more reach you can just get the 1.4x extender. a 300 F4L IS and 1.4X combo would be much more versitale than the 200 2.8. but if you dont care to get that long. and portraits is more your think the 85 1.2 is about unbeatable
