160 hours per month would only be enjoyable for about 2 weeks. Try flying 40 hours logged per week..it is HORRENDOUS.
I do not work for airnet but some advice I would give you is do not go there in their FO program unless you are closer to 135 mins. You can just instruct and build very valuable experience until you get closer to 1000TT which after training shouldnt take much more than 6 months at a great instructing job. Airnet seems like a great job, I just wouldnt want to be there for under 8 bucks an hour building time
