Question on heavy bomber bombloads

[thatguy96]

Are they dramatically different in most cases? I would think that it would only be different in this case with strike bombers (light and medium bomber types) and heavy bombers really have a number of standard loads that you can just choose from. I might be wrong, but I thought that at least with regards to US heavy bombers the loads were pretty well defined by the bomb bay dimensions, not the maximum take-off weight.
