I had CPS send me a 300/2.8 a year before trying the 200/2 and my main complaint about it (besides that I needed a winch to help me hold it) was the poor close focus range. Tight head shots were only possible using ether the smallest extension tube or the 1.4 extender. Also, for typical portraits, I like to have a conversation with the subject, and with the 300 we had to use walkie-talkies ;-)
I agree, however, that you should get a similar look with the 300. Post some of your experiments!
I am sure photog to subject distance will be something to deal with. Just love the look of compressed images from a telephoto...and gods knows I can't afford the 200....
