These mods work well, no crash

About this image

After installing these mods properly, delete ALL the files in this folder:  Oblivion/Data/Meshes/Character/1st_person, this will prevent the notorious 1st person glitch. don't know why but it's the only thing that worked for me after spending hours trying other methods. I learned of this fix from this link:
