A very good start to the thread. When I train someone to the point they are soloed, I then encourage them to now really master their skills with their trainer, i.e., fly the wings off of it to the point it becomes boring, THEN they are ready for that next step, a mild low winger or an aerobatic shoulder winger. The chance of sucess goes up dramatically, and perhaps this person is on their way to having a life long hobby, not something that lasts a few months or maybe a year or too, cut short by frustration from lack of sucess.
