You know you want one - just do it!
The only question is which one. To me there are only two choices, either the 800mm or 600mm, I suppose you could include the 500mm for mobility.
Many people go on about lenses being too long - this is the opposite of my experience, in fact on only 2 occasions has my 800mm proved too long normally it's too short!
I most definitely would go for the 300 f/2.8 IS II because it's not too heavy of a monster and you have the option of extending its range using tele converters. Such a lens would have to get a lot of use from me, and I usually don't have a need for 400mm plus.
I have the 300 F2.8 but, unfortunately, it get far less use than my 800 F5.6 L. The 300 is a great lens and very portable, plus it works well with extenders. The 800 is just better for my uses.
