In various places it mentions that skills suffer armor check penalties for armor and also for weight carried (-1 per five pounds). As I recall, they got rid of the weight carried part of that for D&D 3.5. Is the Conan book in an "in between" state with regard to that rule change from 3.0 to 3.5? In other words, it seems like it should be either armor or weight, but not both.
I hope that makes some sense...
