If the last mod wins where should big mods, like the Unofficial Oblivion patch (that I guess really isn't a mod), Shivering Isle DLC, etc be placed in the load order in relation to smaller mods - for example, a house mod or follower? I'm using wrye bash (standalone).

http://www.gamesas.com/topic/1434397-rel-boss-for-oblivion/ answers all these questions and is the repository of the answer to these things for the past several years.
