I was in your dilemma a couple of years back and I opted for the 400. I have never looked back! The 400 is very sharp wide open and very light. The AF is amazingly fast and touted to be the best BIF lens because of this. Yes it suffers from f/5.6 so you need good light or a very steady hand but I rarely find myself in this situation. Like you I have a faster zoom if I do find I need it (In my case I have a Sigma 100-300 f/4).
Off topic, where about are you in Iceland? I work for an Icelandic company and frequently visit :-)
