Replying to Blends Or??

About me, 50% all mnt jibbing %25 park, 25%backcountry. I'm 6ft 160lbs~ and a pretty decent skier. i'm looking at getting Blends this year for a do everything ski, except for deeper pow/ backcountry i have a different set for that. Does anybody know anything similar or are Blends the best choice for park/all mnt jibbing? Also i cant decide which size to go for, I'm use to 178 but i don't know if i should go to 185? Any help would be great!
