Cheers for the comments folks, I'd like to take as little as possible, at the moment it's looking like the 16-35 II, the 50mm, the 135mm, my Lensbaby and my Eos M !
The comment about not missing the 35-70mm if I had a 70-200mm have given me food for thought, I'd previously discounted a 70-200mm lens on my crop 450D, but now I'm on full frame, I may have to force myself to go out with my 70-300mm non L and see how that works for me. Having thought about this, I'm really enjoying my Eos M as a lightweight walkabout camera, the 22mm lens has of course the same view as 35mm on my full frame and at the moment is working well for what I photograph.
I had a 15-85mm on my crop, it was near on perfect for the range it covered, it's a shame there isn't a full frame equivalent - the 24-105mm is short on the long end by comparison. A new 24-135mm f4 HIS would be in my eyes, a great walk around on a full frame, but perhaps not that popular with the purists ;-) My style is definately bold, I like to use ultra wide close up, I like to get in close on portraits, I like to bold my colours in Lightroom, but of course I'm limited on the style of shot by the lenses I currently own - although I don't at all feel limited by my kit. I've mainly use my 16-35 in the last six months, then probably my 135mm, then my lensbaby, i last used my 50mm on New Years Eve, but not used the 70-300 at all, probably because the 135 works better when cropping in and the 200-300mm range produces quite poor images in my opinion.
I'm err'ing towards keeping my cash in my pocket, working with what I have, making an effort to sell my less used lenses and making a choice in August over a 24-70 2.8 II or a 70-200 2.8 IS II - whichever way, it has been a very expensive year and I'm loving it - my photography style has definately improved since moving to raw a couple of years ago and more so since upgrading to full frame - I'm less snap happy and much more considered, which results in a great big smile on my face when I see the end results.
Now if I could only fix my jpeg output issues - 16bit Jpegs anyone ? ;-)
