i need a new pack, i have a 4+1 cheapy and it's too bulky and the snap doesn't hold very good anymore, i was looking at the reds dimension 3.2 and the 32* freestyle 3.2, for both these packs and from what i understand all these style packs, i need to get get a special belt, which is another $20-25, do i need this special belt or will a regular belt work?
