I have honestly never cooked chicken sous vide. Whole breasts would probably benefit, as they are most prone to drying out.

I'm going to be giving this a try this weekend on fried chicken. Usually I do a deep fry then oven finish, which works consistently and yields nice juicy chicken, but an occasional side-effect is 'bleed' (not sure what else to call it) where blood will leak out near the bone and then get cooked brown in the oven. It's not the most attractive thing, so going to try this other way.
