Forum:Question about level cap on weapons chest on first playthrough

So I screwed myself on "It's like Cristmas" on the second playthrough, so I just farm Crawmerax now. I was wondering what the cap level of the gun crates were on the first playthrough were. I would just go through the game to see myself, but the difference in levels between myself and the enemies makes the game pretty boring. Will I get any bang for my buck by playing through?
