I think I'm going for CoH - it's essentially a character-in-a-box (every time I look at it I think "it even has that?!") and means I can get more creative with other item slots. Infinity is tempting, but I don't like my odds of getting a second Ber anytime soon, and I'd want to put it in a 1.07 ethereal weapon, which will be miserable to self-find. Beast is another good one, but it's somewhat limited in its uses compared to CoH.
Good luck on your surgery next week - how long do you think you'll be laid up for?
