1: Decide on what you wanna ride: park, all mountain, big mountain/powder
2: decide on level of desired performance: beginner(low response), intermediate(mid response), advanced(high response)
3: set a budget depending on how advanced of a board and the type of riding
4: find all the boards from all the companies that fit your criteria and pick the one with the coolest topsheet.
It's eerie how much sense this makes.
