Ok, im finally able to have the time to kill Kimas and making 30k an hour, so i want to know...Whats the best way to raise my stats?

I was thinking Stances/grips due to stopping shot, but also marksmanship b/c of buggy skills in Elite prof.'s

Also, should i raise all Level I then level 2 or raise then 1 branch at a time?
