Replying to 6 feet tall 173 atomic punx???????

I am looking at getting some 173 2011 atomic punx for a pretty good deal. I am 6 feet tall and only around 140 pounds. I am by no means an expert, probably more a beginner/intermediate park skier and im not going to be hitting any huge jumps on them just rails,boxes,regular jumps ect. Are these two small? I know most people say go as long as you can, but would these be fine for some average park skiing and just cruising the mountain?
