I have a lot of Az-truck time, and the airframe on that family is pretty solid (hence Az-truck).
But 160/side is pretty anemic...it weighs almost as much as a Duchess or Seminole with 40 fewer HP. When teaching, make CERTAIN you know...
1) What density altitude you can hold level altitude SE.
2) How much climb you can get after TO when SE at your field.
3) Where to go straight ahead if you lose one and can't get enough altitude to come back around.
4) Spin characteristics of the airplane...you might need them at some point.
Operate with less than full fuel if needed to improve margins.
Private pilots often operate light twins without balanced field or without decent SE T/O climb (they die a lot too). As a professional, you won't be able to get away that in the long run, so you may as well start doing things correctly now...always leave yourself a way out. Just because it's legal, doesn't mean it's safe...
