d90 and 80-200 2.8 AF-D is Great!
I have been wanting to get the two ring version. I had the push and pull and it was great except that from 150-200mm it was soft. Didn't know if it was a lens issue or all of them suffer from the same thing. Anyways, I later sold it because I too felt it was too heaving and big to carry. It does serves it purpose tho if your into wedding or wildlife photography.
