Alright, so here are all my current mods and their load order.
Some are merged with Wyre bash, rest have been ordered by BOSS and then some manually ordered in OBMM.
Also these are just the esps and esms. I have many more retextures and such that dont require a esm/esp but I dont feel like going through them all since they are mostly unimportant to this matter.

Utilities:
OBMM
OBSE
Wrye Bash
OBGE
BOSS
TES4LODGEN

If you have any tips or recommendations on what to add/remove/move please comment.

PS: Also I havent exactly tested this order yet but it is very similar to what I had before but that was caused a few bugs and I hate bugs...
Other than that everything mostly works fine


Thanks

Make sure you are using the most current version of the mods you can get. Install all of the Unofficial Patches, and the Supplemental patches by Arthmoor, You can then drop the Thieves Den-SSSB patch.
There is an addition to Cobl on TESNexus that brings Cobl to version 1.73. Make sure you have the OOO specific patches for the mods you are going to use.
Do not forget to use RAEVWD in combination with TES4LODGEN, I can not give up the scenic vistas on my own game.
Watch out for the latest version of Kvatch Rebuilt, It has been released this year and is very buggy at this point, I am waiting for the author to release a clean version.
You do not need the UOP Vampire Aging and Face Fix, this has been incorporated into the Bashed Patch. The Citadel Door Fix is another esp that can usually be droppred from your Load Order.

If you're using BOSS why is Better Cities. esp placed at the bottom of your load order? I understand that you have manually moved some, but why move that file; its just a dummy esp that loads up the BSA's for BC.

I moved it after looking at arwens mod load order and it said to load after wrye bash (http://amito.freehostia.com/Oblivion/OB-mod-order.htm)
also it does say "Much of this load order is based upon suggestions in the mod's Readme file, or from what others have suggested. Please understand that my load order may not be perfect - but it does seem to work ok in my game (as far as I can tell)." so you may be right. BOSS had moved it to the top form what I remember

I cannot seem to find COB 1.73 (I have 1.72, which is the latest version according to the COBL page on tesnexus
For my LOD I currently use http://www.tesnexus.com/downloads/file.php?id=18497&navtag=file/images.php?id=18497&tab=3 with http://www.tesnexus.com/downloads/file.php?id=9952
this lod package is supposed to be for higher end machines unlike the latter

and I get a lot of my mods from Arwens oblivion site found here http://amito.freehostia.com/Oblivion/OB-mods.htm
both of my UOPs are the most current and for me to be clear I should just uncheck the thieves den SSSB esp and the vampire aging and door fix. i saw this on BOSS but I never did anything cause I never did anything with the patches on Wrye bash

I also have every setting on max along with my ati catalyst for highest quality

PS - Sorry for the double post, didnt see multitquote option, if its against the rules just merge it for me

BOSS is the best tool there is for setting Load Order. The update to Cobl is in the "Drop Loot Merchant changes Proposal", this has the 1.73 update, and it is an optional file in the Cobl downloads page on TESNexus.
I recommended RAEVWD because it is recommended for use with Tes4LODGen, and the options I can adjust for what LOD will show. I have a heavy mod Load for my laptop, and I can adjust the quality of my LOD to keep my game stable.
You should try and get to be familiar with using Wrye Bash and BAIN, the sooner you learn to use them, the easier it becomes to have a stable game when running lots of mods together. The third link in my signature is to the release thread for Alt3rn1ties Pictorial Guide to Wrye Bash, not the actual guide itself.
The Supplemental Patches by Arthmoor are a continuation of the UOP,USIP, and the UOMP.
