Making a 5 pound brisket in a master built electric smoker and will using whiskey barrel Oak and hickory woodchips. Made a paste with Dijon mustard garlic and apple juice to the texture of a wallpaper paste. Seasoned it with a rub and let it set overnight. Set my smoker at 220° with a water pan of beef stock any other tips I should be doing and about how long do you think it'll take to get to 195 degrees?
