I like to take mine to about 195°, wrap in foil for about an hour then in the fridge overnight. Slice it real thin in the morning and vacuum pack portions. When ready to use, wrap the slices in a wet paper towel and nuk for about 15 seconds. Comes out better than what comes from the deli.
Edit: That's after soaking it in water for 2-3 days changing the water every 12 hours.
195, no matter what? Do you use a slicer? I used a carving knife, but there's only so thin that you can go with that.
