Some good discussion! I really appreciate your points. I know longer have a desire to teach several students... at least not at this time. I would think it to be unfair to my sons friends to be basically a training partner/dummy just to better my son. Being my son I fear I couldn't truly be fair and do not want to put a kid in that type of situation, But I may need to revisit this idea in the future. As far as a mat fee, it would be a delicate situation not to be disrespectful. I would hope one would look at it not as a challenge but as a growth opportunity to spar with someone new. I have no problem with him going with a higher caliber student, I would expect that and do the same. Hopefully once the instructor gauges his skill level his students and mine will have an opportunity to get better. I came from a traditional school that did not pump out belts. So I'm not so concerned with him being ranked until its time to enter a competition. At that time I could determine what class he should be in. But for me to rank requires experience which puts me back to square one with finding partners... Man I love the idea of a father teaching his son but I realize the limitations.
