Line Up and Wait
My philosophy is to never generalize based on age. Make your judgement based on the person as an induvidual instructor.
This.
I ave gotten excellent instruction from very young instructors, and "YGBSM"-bad instruction from "experienced" guys.
My decision wasn't based all on age and if I had found a fantastic 19 year old instructor I would have hired him. We have a few (or more) of "young" CFIs here on the board that are well respected. That said, if you look at the majority of advice people give, it's "go find the old guy...or Jessie." My CFI came with a host of recommendations and we get along great, so it's a win-win.
