I have heard good things about the Burton Ions, and if you are rocking the cartel binding, they will match seamlessly.
But honestly go with what feels good. Try em on, tie em tight, walk up stairs, stand on your toes in the boots (to attempt heel lift), squat in them to see how you flex them and pick WHAT IS MOST COMFORTABLE. the best high performance boot may be enticing, but if it always feels like a vice is squeezing your foot, you will HATE them.... most important is: comfort, heel hold, flex, tying method. color and style are not important...they will be covered by your pants and bindings.
