flayed ones

Hello All, HQ 1495 Nemesor Zahndrekh - 185 Vanguard Obyron -160 Cryptec (dest+veil) - 60 Lord (MSS+Orb+WS) - 90 Troop 20xWarrior (+ obyrn + Lord Orb +Mss +WS) - 260 10xWarrior + Ghost Ark (+Nemesor) - 245 Elite 5x Deathmark (+cryptec) - 95 10x Flayed Ones - 130 Heavy Annihilation...

Being new to Necrons and noting that the evil metal monsters seem to be pretty much a shooting army I was wondering about Flayed Ones. I really like the look of well painted Flayed Ones but I was wondering if they are any good in 5ed and what is the best way to use them?

I recently decided that I had too many Necrons Warriors and not enough Flayed Ones for my army. So I decided to hack up a few Warriors and start converting. I know this could go in the painted or conversions forums but I really just wanted to show this to a group who may find the images...
