An update on my CTD issue. After getting it to load last night by removing Obsidian's esp from the merge, I tried rebuilding the merge with a freshly downloaded copy of obsidian and got the crashes again. My previous fix of removing obsidian from the merge didn't seem to work this time. I tried various things but to no avail. I was convinced it had to be the weather system merge but then I tried disabling everything that I did during final step, bash patch, zpatch, smash patch, even dyndolod and lodgen stuff and re-enabled the esps that were disabled by bash patch. Basically resetting to the point right before the finish line. And to my surprise it's able to load with the merge patch and all. So now I come to the conclusion that I must have screwed up somewhere in the finish line and caused some sort of conflict between the merge and one of the files generated during that section. I'm going to try and start the finish line section over and see if I can get it right this time.
