The cub I have is the H-9 P-N-P. The guys I fly with do not have any cub's, but they fly some tail draggers. The one has the Telemaster, I think that's what it is it looks alot like the cub.
As far as flying inverted I do fly inverted, but not close to a whole circuit. Flying inverted is easy for me on the sims, but a whole lot different on the field. With my trainer I am at the point that, don't get me wrong here because I love flying it, I am getting bored with it. I think I have tried everything you can do with one, but I can not say that for sure. I have taxied the cub around some and was able to get the tail off the ground, but never took flight, just working on getting the tail to come up.
I was just looking for a reason why some would say it's not a good second plane, besides just saying it's not. I do like the info. you guys have input. I do think I am ready to fly it and I look at it in two ways. 1- I will try it and love it or 2- I will crash it and now I will be forced to learn to do repair and cover work. I guess I win either way, but i hope I don't have to start learning repair work yet.
