When researching sous vide corned beef, one site used 150° and 36 hours and another used 134° and 48 hours. Since I use 134° and 48 hours when doing brisket flats that turn out well, I plan to do the same for this application.
I just put them in fresh water for a day or so to remove the excess salt but I have not yet decided on the follow-on sequence of events. AmazingRibs.com suggest that you SV, cool to 34°, season and smoke. My inclination is to season, refrigerate over night, smoke and then SV.
