~NS~ I NEED SOME HELP>!

Yo. So i turn to the Ns community. Heres the situation.  I currently have two pairs of skis, one pair of Brand new DUmonts, and a slightly Used pair of Line CHronic Wides with Px12s.  I want to get rid of my Chronics just because i ski almost 99% park and hit alot of rails and the Chronics arent your typical ski for that.  So here enlies the dillema.  I really dont think im good enough to even notice the difference between Dumonts and another ski. I dont think i need DUmonts, because i will admit it, I am not the greatest skier.  I did score a great price on them, which is why i picked them up. My intentions for this year were to have two sets of skis, but i realized i dont ski nearly enough, or am near good enough to have two sets.  So, I get rid of the chronics, and ski the dumonts? Or do i sell the dumonts on ebay for some profit and buy some invaders ( a great ski to dick around on, hit rails, and not give a fuck about kicking the shit out of em) and new boots? B/c i pretty much just wanna fuck around on rails and little butters and what not. I cant really hit big jumps b/c of basketball season which kinda blows, so i dont really need a great "jump-hitting" ski. what would you guys do?
