Jesus.... You're 12? Your the same height and weight as me and I'm 18.... Anyways, never ridden either but lheard great things from both. The ON3P's are likely going to be more durable and last longer but Armada still makes a quality ski. Can't tell you anything about the acctual ride though. Good luck with the decision man!
I ski at park city, I mostly ski park and maybe a little bit of pipe sometimes. I got third at jr. olympics this year so i am a pretty good skier.i like to ride a soft ski and i also i like to ride them long. thanks for all the help guys.
