Replying to Line Blend - 178 or 185?

I'm considering going for the Blend as one-ski-quiver but I feel uncertain regarding which length I should get.

I'm approximately 6 feet (183 cm) tall and weigh around 161 pounds (73 kg).
I currently ride the Liberty LTE (2012) at 178 (specs: 117-87-106) and feel like this size is right for me but I know that the early rise in the Blend will affect how they feel riding and how long they should be (right?)

Will the 178 be too short or fine? Are there any other aspects I should consider when switching from a ski like LTE to a ski like Blend? I wish to ride this ski in the deep and on the slopes but I prioritize that it works for me in the park which is why I'm a little scared of buying the 185 - it seems a little too long for me (I do rails/jibs way more than jumps)

Sorry for the kind of long post and huge thanks for any advice!
