When I do a whole brisket, I separate the point after smoking. I let it rest for about 30 minutes. Usually I do the burnt ends at a later time. I cube the point and vac seal and either freeze or refrigerate depending how long it will be until I do them. When I decide to have them I thaw if frozen, season and add my bbq sauce of choice. I put them back on the smoker at 225 and give them another hour. I've never been disappointed.
