Interesting opinions. The flexiblity of the 70-200mm 2.8 is just splendid, while on the shoots I'd definately go for a 35/50/85mm 1.4-1.8 with creamy bokeh because of the problem with finding varied and good-looking backgrounds on the Con.
A macro lens would make for some interesting shots on props or armor too. But I've only tried one proper macro lens so I can't say I know much about them..

I guess you'd prefer like a 35mm then? That should just about be enough. I found it suiting me much better than an 85mm though I liked the amazing distortionless pictures it produced when taking a few steps back. So many choices xD
