the advantage is the skier is being pulled from a higher postion thus making it easier to get more air over the wake, but if ur new at wakeboarding i doubt u would be conserned with that, but a higher tower or pole does make it a lot easier to get up out of the water also
and to aide in jimmy's sell that is a nice board for a 100 bucks even if u only plan to use it a few times, many places charge more then that just for bindings
