For most new pilots just starting out a Stik makes a good second plane, but the trainer must be completely mastered first. I would not suggest a Stik for training unless the person has reasonably good skill right from the beginning and a good instructor is on the buddy box

If you cannot handle a trainer in wind then a Stik will be a handful even as a second plane. Almost all Stik's have a nice big "Hershey Bar" wing and as such tend to not slice through the wind as well and will float forever. The bigger Stiks like the 60 and 120 sizes are much better in wind because of shear weight and size but the 40 size is shall we say a handful.
