Put more money in the pot and get and get an LS4, Pegase, Discus etc. Not are they easy and pleasant to fly, they have enough performance to make it interesting. They can also be flown badly and still perform well. If that is too much, a Ka18 may fit the bill (if you can find one). The older and less capable aircraft (Libelle, Astir, Vega) are exactly that and you will outgrow them.
