It all comes down to size and rigidity. You'll be OK if it's a little smaller yet stiff enough for your weight. You'll have issues with heavier impacts if it's too long yet too soft. Try not to go by brand or model, as there are lots of different makes and models on the market that differ significantly in quality. Generally speaking, the longer the board, the more difficult it will be to turn. This is because you'll have more distance to travel before you reach the edge. To make up for this, you need a board that is both very flexible and has a relatively large surface area. The best way to find out whether you like small boards is to try one out under normal riding conditions where impact forces are not an issue. If you feel comfortable on it then it will be suitable for normal winter riding. Snowboards are used for recreational purposes so quality should be considered before price. Look for straight edges and solid construction. A plastic core will make it lighter yet still provide support. A foam center may look nice but it won't help when you hit a bump. An aluminum core will be stronger yet heavier than a plastic one. Don't worry about having different sizes of holes in the board for binding adjustments; these are called "camber" and most small boards have it. Camber changes the angle of the board at each end to facilitate turning.
