I am 5'11" and am a big fellow (about 230). Just finished and approved my TD with the 501st (not MEPD PD yet, still waiting on a Hopper Pack, which he has kindly been working on since March, can't wait!). I bought the Anovos kit and felt like I looked goofy in it, so I went with AM 2.0. That kit was much better. Not only was it bigger and a great fit, it was also pre trimmed (which saved a ton of time). It is made of substantially thicker material, which makes the Anovos armor look like paper.
Here are my photos (not saying I look great, but I feel well enough about it as a bigger dude):

Also, if it helps, I found this thread by Navajo Bro to be invaluable for an AM kit:

The contact for an AM 2.0 kit is: troopergear@gmail.com
Hope that helps, and good luck!
