Replying to K2 domains vs. atomic punx

Ok, so i'm having a really tough time deciding wether to get the domains or the punx. I primarily ski park, but ocassionally i'll ski some woods trails or groomers. Both skis seem like really good skis and really buttery, which is what i'm looking for. I primarily hit jumps 40 feet at the biggest. It seems to be that the punx is a little bit lighter then the domains, so i'm just a bit worried how much heavier the are. Lastly, i'm about 5'9" and about 140 lbs.

Thanks for reading and anyone that helps!
