The age-old issue is that carving ability and powder flotation require contradictory characteristics. There are lots of ways of working around this and many skis that are solid in both areas, but to excel in carving, you want a narrow waist and a stiff ski. To excel on powder, you want a softer ski and a wide waist. Very broadly speaking.
If you want one ski to "do everything", you will need to define what "do everything" means in your case and where you are more willing to compromise.
Unfortunately, almost every ski you see advertised claims it can "do everything."
Your Bandits are, what, about 78mm in the waist? If you want more carving than that, you might look at a Mach 3 or a Tigershark. If you want more powder flotation, you might look at a Watea 84. But to get more carving AND better flotation ... unless the B2 is a poorly designed ski, that may be difficult.
