So... I've got fcom(without using Francesco) and I'm wondering which overhaul I should use for Shivering isles

I saw that there are available

1) The francesco Shivering isles option, though I don't know if I can use it without the main files

2) MMM Shivering isles

3) Zuskunks OOO overhaul http://www.nexusmods.com/oblivion/mods/34245/?tab=2&navtag=http%3A%2F%2Fwww.nexusmods.com%2Foblivion%2Fajax%2Fmodfiles%2F%3Fid%3D34245&pUp=1

What would you advise? Do you have other tips to improve the shivering isles?
also, does OMOBS exist for SI? or at least MOBS?

edit: well, if you can, link also stuff that you find good to have in your SI game . I didn't find many SI related mod >.<: just the root system mod, that is worth adding.
