Replying to Id love some help

i skiing east coast..i wanna have a fun responsive ski..rails, big kickers..everything..and im struggling..im 5' 9" 160 pounds...and heres my thing..all 2008 skis

chronics 176 but think they will be stiff and heavy
and silencers 179 but worried about durability and weight
now call me gay and stupid for posting this...but ive saved up alot of money for like 8 months and i would liek some person input from people who have ridden the skis..or just opinions...thanks
