I can't think of any other reason that you could fold a spare tubular and pull it apart.
Regarding rim weight vs. 'other weight' it is a function of why you care about weight. If it isn't about accelerations (IOW mostly about climbing) then it doesn't matter. But if your concern is more about tracking the accelerations of an aggressive group in a crit or whatever, then yeah verily.
If I am incorrect on either of these points, I'd be interested in a better understanding - thanks.
