The NB will get lost in there.
Use the Magnum to bitter, be it your 60 min addition, or FWH.
Use the Columbus or Centennial for the flavor additions, and toss in the Citra at flame out.
Problem is.. for a DIPA, you need more hops. An oz of those aren't going to do much of anything.
I'd do.. 1oz of Magnum FWH
.5 Columbus @ 15
.5 centennial @ 10
.5 Citra @ 5
.5 Centennial @ flame out
Use the last .5 of Citra to dry hop with, and get something else to toss in with it and make a simple IPA.
