Going to Vancouver BC Pro Store

[Spam.n.Rice]

Some of my friends decided to have a trip to Canada this weekend and I'm very excited just to go to the MAC Pro Store on Robson. However, I'm not 100% sure if I am going but either way I will be getting stuff there. Anyways, I was just wondering what e/s should I get? I want to balance out my collection. Also, would it be better if I got the 15 pan pallette than the 4 pan pallette? Here's a list of what e/s I have so far:

Arena
Bamboo
Blu Noir
Carbon
Fiction
Freshwater
Guacomole
Parfait Amour
Scene
Shroom
Star Violet
Steamy
Sweet Lust
Swimming
Swish
Tempting
