Replying to Good jump ski

Alright so I was gonna get some atomic punx but then I thought that there going to be big on me. Im about 5'5-6" and I weigh about 130-5. I am 15 years old. I ski park 95% of the time and I usually make 1-2 trips out to the mountains each year. I Ski about 65% jumps and 35% rails. I really want to progress on jumps next year. So far I have my eyes set on Alpha 1s but still need some help. If I get punx in a 173, would they be way too big? Thanks dudes.
