Rush or Reignover Week 7

So Week 7 is coming soon and I'm torn between my jungler. Reignover is a very good player and scores quite well most weeks but next week is probably one of Fnatic's hardest weeks, against Origen and H2K. Although Fnatic will still probably win, Reignover has a tendency to die, a lot. I also have Rush as a sub and since TIP is playing DIG and T8 next week, it should be quite easy for him. I'm not sure which one to start, thoughts?
