Replying to 05-06 triplets with NEOX 614 bindings (Opinions?)

alrighty then. This weekend, I bought the forementioned 163 triplets with bindings at the "Mammoth Mart" for 90% off, ending up being about 200 bucks for 3 ski's and 3 bindings. Right now I'm skiing on (don't laugh) elan M02's form 2003/4 ,so i'm used to the "3rd rail technology" on rails and boxes and stuff.
I can slide most rails with my Elan's, so I'm not worried about how the extra edges will do on the triplets. I am wondering about how the flex is going to be though, they seemed pretty solid in the shop. I'm not awesome in park, and I mainly ski all mountain anyways, so it's not a huge issue, but do the ski's flex that well, or are they as stiff as the elan's?
