This board is you go to board when you’re not sure what you want to do. Take it on a trip and no matter what the conditions you'll be faced with this ride will definitely keep you in track; it's a lovely board to ride with a quick response and a good turn radius.
The custom has stood the test of time (with numerous updates over the years) and continues to be the comparison tool of the snowboard industry. "This _____ board rides kind of like a Custom but a little bit more _____."
There are a lot boards from other brands that can get you this ride/performance with out the price.
The Custom X (and wides) has more power and edgehold for more money at the register.
