Hat you've covered. It's obviously an important item (one that I'm still working on myself).
Body is great for looking good in town, but not a whole lot else. If you need the ACC you can get a Scorp Harness; it's probably much easier to do so anyway.
Hands are a decent RACC piece. The only pieces with more are Enkidu's
, and Crimson
Legs make a decent Detonator piece, not sure about Slug Shot, though. I don't use them for Slug Shot, anyway.
Feet are the highest ACC COR can get in the slot, save Commodore +1. I use them in situations where I'm missing too much for Haste to outweigh the ACC.
Just my two cents on the AFv2.
If you can't have the otter, go for the derby.
