Replying to Quiver for BC skiing

Alright guys moving out to BC this year and i need some help getting my quiver sorted out! I will be moving to Kelowna so my main resort will prob be Big White! looking to do trips to Revy and other places too. So far this is my quiver. I have two pairs of boots so ill include what boot im using with each ski!

ON3P Billy goats 191cms (118mm Underfoot) W/ Marker Dukes EPF - Scarpa Maestrale Rs (AT boot)

Volkl Mantra 184cm (96mm underfoot) 184 with Look px 12- FT classics with my #10 tongue

Coreupt Bangers 184cm (90mm underfoot) Do it all Park ski- FT classics with 6 tongue

Armada Halo 171cm (81mm underfoot) Look pivot 12, Pipe and rail jib ski- FT classic with 6 tongue



So my Question to everyone is Should i get rid of My armadas or coreupts and get a ski around 105mm underfoot?

And if i did what type of binding should i put on it? I'd like to get a free heel binding but not sure if i could get a dynafit and just rock it in the resorts?

What are everyone's thoughts about getting a light twin tip (105mm) and putting say a tour 12 or baron on? I'd still like it to be somewhat stiff for bigger mountain stuff! let me know what you guys think.
