I understand your desire to get somthing that looks like a real airplane. But, the Cub really isn't the best choice for a second airplane. Could you build it and fly it, yeh, but you will have much better results with the other planes mentioned.
Any brand of "Stick" airplanes such as the Ultra stick series, the Kange Sk-50, or Goldbergs Tiger II or Tiger 60, Sigs 4-star series would all be much better choices for your second plane. These planes will continue to teach you to fly with confidence and at the same time are really fun to fly.
Consider buying a "stick" ARF, assemble it as a tail dragger and fly that while you take your time and build a really nice Cub kit. When the Cub is finished your flying experiance/skills should be ready for the unique characteristics the Cub will display.
Remember that you will get a lot of different advice here in this forum. It will come from folks of all experiances and flying styles. Some of them are flyers who on take off, move the left stick all the way up and never touch it again until its time to land and others enjoy the smoothness and precision of the aircraft and the relaxing quality of a GOOD flying model. Being a good pilot is more than slamming the sticks around and stressing the airframe!
