Recommendations for Base, Mid, and Heavy Layers

FOR KILIMANJARO...Patagonia Capilene, SmartWool, Under Armour, Icebreaker, Chillys?????

Which do you prefer best for base layer, mid layer, and heavy layer? Im having a hard time deciding for Kilimanjaro. If you have a specific recommendation for each light, mid, and heavy...please let me know...if you you prefer a specific brand, please recommend?

I may consider combining different brands..one for base laser and a different brand for mid layer...or using only one brand. Id like to hear which ones you like best and least and why? Thanks.
