I have both and they are both great. I've had both of the Mammoth IPA and IPA 2.0s and they are bomb proof. I think they will literally last forever. The compartments and skate holders on the Pacific Rink bag are fantastic, none of the little tiny thing's ever get lost in the bag. The only down side to the Pacific Rink bag is that the buttons on the strap handle always come undone when I lift up the bag. Its a small little issue but an issue none the less. With that being said I would lean toward the IPA 2.0. Its the second iteration of the bag so they had a change to work all of those little issues out.
