looking for a site for gear weights/rankings

like the title says i'm looking for a site to give me some idea of the value for various bits of gear for my prot warrior, saving me from doing all the math myself. i'm aware of both mr robot and max dps, however both have conflicting lists, and both have outdated or simply wrong idea's for warrior tanking. leading me to question how valid the rest of what they say is. the warrior is only just about to become my main so i'm sort of playing catch up here. any help would be appreciated.
