All I can say is that I have ST for about 3years now and I think it's a really good all around flyier. It will fly both, 3D and pattern. I have YS110 in the nose which provides plenty of power for anything you can think of. I fly it without SFG's 'cos I couldn't be bothered putting them on all the time. The plane flies great without them as well. See people have different opinions. I guess it also depends on your flying style.
