Which yellows to keep and which to sell?

Thanks to one month league yellows are dropping like candy. In any particular low level map I can get as much as 30 yellows, and I vendor 99% of them for alt shards. I have SOME understanding of what rolls are "good enough for selling" but still not 100% sure. In party runs you really don't even have enough time to ID every single yellow that drops (and a TON drops).

So here are what I believe are the rolls that people want:
- Generally at least ilevel 50
- High +HP roll
- +100% or more armour/ES
- Tri-resistance with at least 20% in each resistance
- Dual-resistance with chaos resistance
- At least +100% physical damage for two-hander weapons
- At least +15% cast speed combined with at least +50% spell damage for wands/sceptres
- +2 level of socketed gems for weapons combined with +fire/cold/lightning damage for wands/sceptres
- 5L or 6L obviously, or maybe 6S4L

Any others criteria I'm missing? How about jewelry? I'm never sure which jewelry are just NPC fodder and which one is a gem that might be worth like an exalt.

Is this like some kind of trade secret..?

my question is... Why are you identifying and selling unwanted yellows for alt shards when you can leave em unidentified and sell em as gear sets for 2 chaos orbs?

I'm already keeping sets for chaos orb recipe, just didn't mention it in the OP cause I thought it was irrelevant. Obviously I can't keep hundreds of yellows in my stash because you only get 4 tabs. I've already sold like 30 sets just from this one month event alone, and I only play like 1-2 hours a day.
