As an addendum to my original post, regarding SoD:
SoD and PoP are my two favorite mods from M&B Vanilla. SoD for Vanilla has the most advanced features of any mod I've played for original M&B. Unfortunately, the person responsible for creating the original SoD is no longer modding, and those who have taken over the SoD mod for warband have yet to produce a playable mod that has features anything close to the original. SoD is still a work in progress, and PoP is a completed mod. So between the two, as far as warband mods are concerned, there is no contest at the moment. My advice would be to play PoP for the moment, and keep an eye on SoD for updates on their progress.
