All my experience with Northern lights, the plants are very leggy and tend to creep out. Its good smoke reminiscent of skunk #1 with the way it grows and tastes. Its an oldschool breed. The Jack may stop the leggyness. I don't know about the yields though. Sounds to me like you are looking for a Hashplant or Hybrid, some good ones have been mentioned
Edit_ - I myself would personally love to grow a Great white Shark out from Shantibaba. That strain kicked ass!!! , Way better than Rhino.
