I do have a Burton board, but I am not 100% sold on the Burton product. I am not saying Burton is a slouch product, because they are not, it’s just there are other new brands that put together a nice board as well and may have design patterns that are sweeter.
There is no harm at looking at the Burton flagship store especially if you are a new border, they would probably fit you better for a board. Most local ski shops are still more geared to selling ski equipment and are selling boards because of money.
Local Ski shop will mostly likely have a larger selection of other manufacturers. However most local ski shops are still more geared to selling ski equipment and are selling boards because of money. Local Ski shops may be a less expensive route for buying a board as well.
Good luck! I hope this helped
