While making my own CFI lesson plans, I realize that every lesson plan will not be perfect. I can't help but wonder if purchasing lesson plans from Sporty's, or whoever, will help ensure my coverage of a given topic is comprehensive. I do only intend to use them as a SUPPLEMENT to my work, NOT a replacement. I wonder if any of you have found purchased lesson plans to be beneficial and if so, which company makes the best (in your experience, of course)?
