You might consider getting a Roto Grip bag. Comes with a 5 year warranty. And the Roto Grip/Storm 4 ball stackers are really rather short. A lot different and shorter, with plenty of pockets, than my Track four bagger. As is I use a four bagger and a two ball tote every league. Just like to have options I guess. Rarely use more than three bowling balls, including spare ball, usually only two total...one for the game and my spare ball. But you never know!
