Oh jeez, as others have said, on trying to learn on a 197cm Burner. I just got one after about 15 years of carving, I had to be pretty careful with it; not user friendly at all in my opinion - like riding a motorcycle with a larger rear tire; just wants to keep falling into corners, and hard to bring back up. I've only had one day on it so far, so no disrespect to the board, I probably need more time with it.
If you can find something in the 160-170 range, you'll have a better time learning. I don't know much about the Volkl, but even a 180 ish GS board can demand some space to ride until you build some confidence with it and you start riding it, and let it stop riding you.
