Stand bag for me at the moment (Titleist Staff Stand Bag), but in the past have used a staff bag, mainly to take the pressure off my neck and back when playing a lot.
The local pro shop currently has a Callaway Rogue Staff Bag in stock, and whenever I see it I go weak at the knees, as it’s just so pretty. Must. Not. Give. In.
Stand. I spend too much time at the range to not use a stand bag.
