We advertise 17 because it's the perfect amount where no discs are really getting in the way of one another. But yes, you can fit more..
Now I'm only showing this to you guys because it's my job to push my bags to the absolute limit to see what they can do. Plus I thought it would be fun to show you a Shift actually stuffed
This is 31 mids (Buzzz) inside a GMC v4 Shift.
As most of you know, this is not realistic. The inside discs were impossible to pull out one at a time but the outside pockets still worked surprisingly well.
That is awesome!
