Replying to Park Skis for next year

So I have been rocking Line Chronic 2016s for a few years but it really seems like it is time for a new pair of skis next year. I really like lines but their durability is just not something I like. I want a ski I will be able to use for longer than 2 years because I only ski around 30-40 times a year and those trips are on average 3-7 hours each. I was thinking factions, armadas, or ON3Ps but the price on them is pretty steep. Any suggestions on what I can do as a high school kid with not much money to spend. I am around 6 foot and 150lbs so I was thinking 170-180s. Also I spend about 90% of my time in the park and I am basically in the middle of PA so I go to places like 7 springs, big boulder, and a few others. Hope you can help, Thanks.
