FWE is great, I'm having a lot of fun with it. A few comments/suggestions/bugs, though.
1. Carry weight is a bit buggy. I've noticed that my max carry weight has been slowly decreasing. My standard loadout is Talon Combat Armor, Shady Hat, and Wasteland Explorer Goggles, the latter of which weigh 1lb each which may help in figuring out the problem. I have the option on that gives you a bonus to carry weight based on what armor you are wearing. First, when I equip or unequip armor, the game seems to get confused. Sometimes I unequip it and my max carryweight goes up, sometimes it goes down. Unequipping and re-equipping my hat fixes it. Except, however, that sometimes when I do this my max carryweight falls by 1, permanently. I was wondering why I was having a harder and harder time hauling stuff, though now I'm just going to disable the option. Also, at this point going into the FWE menu and changing how max carryweight is calculated does nothing.
I will try your method, but until now I was not able to reproduce weight bug. This thing simply refuse to work incorrectly.
Long time ago I had problems with weight, and with stats too, but now- no. That force me to think it is connected to incorrect work of scripts under some circumstances- probably due to instability between the game and computer system. Do you have crashes often? Do you use quick load?
5. Track Star/Olympian perks. These seem way too good. I can't really imagine making a decent character without getting these, and that means to me they are probably overpowered.
For me it looks just fine
This perks are in need if you often use bullet time, but not all gamers use it often, so they don't have this perks.
6. Tag skills. I'm not really a fan of tag skills getting 2 for 1 when spending skill points. Basically, for the same reason I mentioned regarding bobbleheads, as maximizing the gains from tag skills requires some annoying min-maxing contortions. It would be nice to have an option to revert this back to the way it was, especially since the Tag perk isn't retroactive (I assume, correct me if I am wrong).
It was maded with respext of original Fallouts and I disagree with you in your opinion. If you think you have too good progress in the skills- you can choose less skill per level scheme. Or I don't understand you.
7. Extremely fast respawning. In the DC mall, I killed a bunch of mutants, then walked through a door. Seeing more mutants inside, I turned around. Immediately all the mutants I had killed outside respawned all around me. Also, there have been occasions where I have saved and reloaded which caused things to respawn. Further, I am fond of the http://fallout3nexus.com/downloads/file.php?id=6645 mod to keep my things organized. Teleporting there and back has caused things to respawn.
Respawn occur due to respawn settings- no more, no less. Problem, which you described, probably of different nature. Sometimes in the areas with too many actors, spawn occur not fully. Some number of enemies appear with delay. In this case, during your next visit into area, you will meet with latecomers. This problem not from FWE, it is from vanilla. I was able to see it in vanilla even before MMM.
I'm not sure why any of this is, but being punished for saving and reloading is problematic in a game with so many CTDs.
If your game have many CTD-s, it can explain your difficulties with inventory weight and another things. If you have multicore CPU with more then two cores- try to downcore your processor to 2 in system bios setup. It must help
And thanks for your opinion
