Fool's claws

One for the PvP/WW assassins out there:
I know you like your fool's

Claws but what exactly do they need to offer to actually be worth anything?

Specifically:
1) What bases are of interest?

Blade, greater and/or

Runic Talons?
2) What additional affix(es) are critical vs. desired vs. ok?
3) What staff mods are critical vs. desired vs. ok?
4) Ethereal vs. non-ethereal?
5) Realistic price ranges?

I noticed that even with ladder pricing, a (from the naive outside perspective) rather "mweh" seeming pair of not even elite fool's

Claws was sold for

Jah +

Ber a month ago which brings me to the conclusion that there might be more interest in a larger variety of these than I would have anticipated.

Getting quite a few of them lately so just curious which might be worth listing and which to just get rid of.

Appreciate any Insight from those more familiar with them.
