Replying to NEED HELP!

Hey pplz, here's my situation I'm a fairly new park skier just started this year so I got some 2011 line afterbangs and some cheaper marker bindings (thay are pretty heavy), so i learned to just grind some rails (straight and down) and 360 and a couple of grabs on just smaller jumps so I think I would consider myself to be an intermediate skier now and looking to increase my bag of tricks. But I would like to get some new skis with a lighter swing weight because when I was learning 3's I felt like the swing weight was pretty heavy (maybe im just not used to it) I also want a fairly soft ski for learning butters (which the afterbangs were awsome for) but I don't know what I should try. (Im cool with getting a whole new set up just got a part time job :D ) and I heard there are also good deals on skis at this time of year so PLEASE HELP! 15yrs 5' 9" 170pds (I know I am a bigger guy LOL) If you need any more info on my riding just ask, any suggestions helps! THANKS!
