If Ellis is looking to use 'new' talent I think Alec Worely would be worth a go. He's a very clever writer and I think he has the right mentality for the line.
Also he's worked with Jon Davis Hunt a few times so if Ellis was looking for a recommendation it's possible he could have chatted to his artist.
I hope Spurrier is not one of them. I'm really struggling with his work recently. It's the flow of his books that feels off, always has been the case.
I read the first 2 issues of Hookjaw, which I was really excited about, and I couldn't make it thru the second issue. He tries to be too clever for his own good forgetting that there's a story to be told at the same time. His Crossed Plus 100 also put the nails in the coffin for that series really quickly.
