J-3 Cub as second plane?
Maybe I missed it, but what I didn't read about your first plane.
Assumming your first is a trainer, you may want to consider the GP Easy Sport. It is easy to fly, does all the manuevers and is priced right.
Cubs are great, I have the GP 40 and enjoy flying it, it's relaxing but it doesn't have the flying capabilities of the EZ Sport.
