I've been stockpiling way too much throughout my playthrough, visited too many places, and now I just got a Daedric Battle Axe, pushing my burden over the limit. And I've refused to sell or discard anything that I wasn't absolutely certain I wouldn't ever need, but now that's going to have to change.
I'm playing a combat oriented character, with very limited magical ability (69MP, lots of cheap spells, several with 0% success odds), and some enchanting ability. So far, heavy axes and elemental enchanted blades have served me well, I wear heavy armor, and my most used magical items have been a belt of healing and a wizard's staff with levitate.
Step 1 in my plan is to get rid of redundant magical items. I've found all the spell effects I have multiple ways of casting, grouped the methods, and anolyzed them a bit. Please read my anolysis and let me know if there's anything you disagree with or think I should think twice about.
Here's the result:

Please let me know anything you'd challenge or add to this! Or if you think this all looks reasonable, let me know. Much appreciated - my gaming OCD is crippling me!
