Replying to Powder ski size

I ride 171 blends for park and then rip all mountain with 176 Kartels. I want a pair of candide 3.0s to start getting into backcountry type places like tucks but also have a ski that is good for all different types of powder but still can do fine on hard pack and groomers if need be. I was wondering if 182 is to big. I know people that are 5"9 and ride 182 park and Cody Townsend in his recent video who his 6"2 rides a 192 powder ski as a professional. I seem to like my skis a fairly average length and im 5"8.
