Replying to Looking for that East Coast Freeride Ski

Hey NS, looking for a directional ski for some east coast freeriding. I currently have 171 Line Chronics for park but I hate charging hard on a center mounted ski and they feel pretty out of place on some of the east coasts "burly" terrain like Tuckermans and the like. Im 5'7 and weigh about 155, im an advanced skier looking for something to rip tight tree lines, some cliffs, and some moguls, in less than ideal east coast conditions. Preferably something stiff with a little bit of rocker. Ive been checking out the ON3P Wrenegade 88 in 174 or 179 but I feel like I might want a little bit more waist, any thoughts or reccomendations would be great, thanks!
