Where should I put my expiring 5* skill sigs?

I’ve got a little over 50 skill sigs in my overflow because of the current side quest. I’m hunting aegon so I’ve been saving them but now some of them are expiring. I’m going to open one mutant/skill dual tomorrow and if I pull either aegon or falcon I’ll put the sigs into them with a gem I have. Here’s my current skill roster, if I don’t pull the above mentioned champs where do you guys suggest I put these sig stones? Thanks.

And if anyone is curious, all of my awakened skill champs are at sig 40 or lower. Oh and pretend stealthy isn’t there; I have a 6* that I’ve already invested in so I don’t want to use them on him.

I would personally put in on Killmonger .... high sig helps him a lot .... plus he has solid synergy with good champs like void....

KM if you use him a lot, since he's already ranked up. Xbones is a nice look, but it's a shame his Tenacity activation rate temporarily drops after every purify.

(Killmonger)

Riptide

You could put them into fury just cause he’s one of your top champs

Killmonger, Black Panther OG and DDHK .. the ones I can think of with a great benefit with sigs

Squirrel girl for prestige.

Km or xbones

Id probably use them on fury if they are expiring anyway.
