Hey Missy,
I love the 239 though in regards to the 272, I prefer the 275 myself - perhaps because I have big eyes and I find this helps blend a little better overall.
The 129 is great, I actually use it for dusting off excess shadow or major blending of the eye area. It is a little small for a blush brush IMO but nonetheless still a good brush.
The 180 is a must have. If this is all you order, get this one for sure. Better than the 187 for blending foundation, imo.
I dont own the 136 or the 192 so I don't know what to say other than I can't afford them right now
The 168 is one of my faves. I really think it is a must have.
Hope this helps!! Can't wait to see - post a pic! I am a major brush nut, too!
