Which do you think would be a better father for an Alaskan Ice mother?

Hello, I was wondering which one would be a better father for the seeds of an Alaskan Ice mother, Swazi, Citral, or Chrystal? All of those are Nirvana strains. I am looking for both quantity and quality. But the quality would be a larger factor. If you have a suggestion on a different strain for a father, a strain thats seeds are not very costly. Then please post a comment. Thank You
