So I am trying to determine whether or not to do the CFI (and potentially CFII) in my Cherokee 140 or at a flight school with a 172. Maybe I am overthinking it, but I'm thinking it might be best to do the training in a 172, since that will likely be the plane that I will be CFI'ing in (if I go work for a school). Also wondering if a school might not hire me if I had only trained in a Cherokee and didn't have any right seat time in a 172? The upside to using my Cherokee is that I would save some money using my own airplane. I'm open to both options. Another advantage of the Cherokee is I can go up as much as I'd like in the right seat and practice teaching my dad (Private Pilot) the Commercial maneuvers. I'm thinking I can be pretty well prepared for this before I even really go up with an instructor. @Walboy (CFI/CFII) has kindly offered to help transition me to the right seat in my Cherokee before I start going up on my own in the right seat. What do you guys think? Thanks.
