Assuming you ride the 179 Hellbents, EP Pros are similar length, slightly softer but they hold a bit better edge in my opinion thanks to the early taper. They will be very soft for you though. If they came in a 175 I would buy them as my park skis for sure, I loved them as my all mountain ski, they were just too soft for charging and too long for me in the park.
For reference I'm 5'9 and 135 and I ride Lizzies in the park and Bent Chetlers as my daily skis.
My Elizabeths are 100+ days used now though so I'm actually in the same situation as you.
4frnt YLE and Surface New Life seem like good options but I have concerns about the edges of both. Not hate on them as pow skis but both brands have had shitstorms kicked up about edge durability. Whether they warrant the hate or not I don't know.
Moment Ghost Chant has insane rocker. If that doesn't bother you I'm sure it will be a solid flexing ski with great durability. Both my pairs of Moments were absolutely bomber.
Line EP Opus might also be a good choice. Stiffened from the EP Pro days but probably still won't be all that stiff. I'm thinking the 178 might be my Lizzie replacement/one ski quiver next year.
there's a certain point where it neither looks good nor functions properly...that's when you know you look steezy - no_steeze
