Too many artifacts

[Colbey]

So I've gotten further in the game than I ever have (cl41, ~2600'), and for the first time, I'm not so eager to play. Even when I was always dying after getting what seemed like really far but before cl15, I would be frustrated for about 2 minutes, and then start a new character. But now, I'm frustrated enough that I rarely play.

The problem: I'm finding too much good stuff! I'm selling the obviously junky artifacts and almost everything equippable and non-artifact, but I still find myself in the town with a full house and an almost-full inventory and no idea what to get rid of. See, I'm a pack rat in real life too, and I'm overanalytical. And I just don't really have a good sense of which of my character's things are good and which are only mediocre. So I could make up a spreadsheet to decide what the best armor configuration is, but then I think that I should just keep THIS around too, because what if I find rConf in THAT instead, and then I can wear this other thing instead, and then that other thing, and oh I guess I have to keep everything. If I get rid of anything, then I can NEVER CHANGE MY MIND!

And even if I figure out what to do at any given moment, I don't really want to make the spreadsheet and update it every time I find a new weapon.

So, any specific advice for my character? (http://angband.oook.cz/ladder-show.php?id=7591) And any general advice for this kind of situation? Maybe some resists I really don't need to worry about, or a list of the top artifacts, or just a general way to reassure myself that selling my 5th-best body armor isn't the end of the world, so I can go back to diving and collecting stuff?

Thanks!
