Help me decide

this is to deal with high
def infantry.
35 points
Grim Angus or Jarl Skuld (*6pts)
* Troll Impaler (5pts)
* Dire Troll Bomber (10pts)
* Rok (11pts)
Trollkin Fennblades (Leader and 9 Grunts) (8pts)
* Trollkin Fennblade Officer & Drummer (2pts)
Fell Caller Hero (3pts)

With Marked for Death and his feat, Grim could make a unit -5

def infantry. I'm leaning towards Jarl but would like to hear what people think
