I would say forget the 4* and Tiger (sorry guys) ... move on to a full acrobatic plane or 3D now since you have experience on a low wing. The Funtana 40 is a very nice plane to fly, flies great on a 46 2C even but don't expect to do musch 3D on that set up. I flew mine on an SC46 and then a Saito 72 ... you will love that plane as it can be totally nuts on high rates or fly as an intermediate plane for almost pattern and acrobatic on medium rates. Landings and take offs are totally easy ...

Most important ... how much do you have to spend and what do you really want out of this hobby? I love planes that can snap roll and are fully acrobatic. What do you like?
