Bag Recommendation: Flipside 400aw vs Classified 250aw

[rpm]

Currently have a Flipside 300; it has been outgrown a little by the introduction of a film camera and a 28-70; wanted to know if i should keep with the flipside design for security or go for the classified easy access (250aw cause of laptop compartment). atm i'm fairly undecided which way to go between the two. my main concern is whether the weight on the classified might not be evenly distributed and was wondering if anyone has any comments in that regard?
