This board is made for bigger radius turns that can be found in a giant slalom race course. From experience, I have found that transitioning from a more slalom appropriate board to a giant slalom board can be difficult. But it should only take a day or two to get used to it if you are comfortable on your other board.
Also, since it is longer, you are going to have to make sure to stay balanced. If you get into the backseat, the board can slide out from underneath you. If you are too far front, then you can also slide out or just simply over-pressure the nose. You will also need to put a lot more energy into the turn to actually carve compared to a slalom board. But, if you don't use that same amount of energy to get out of your turn, then you might find yourself in the trees.
Hope this helps.
