That's a tuffy. As long as your thin you could wear any of them. If your going to troop, the AP is good and sturdy and pretty accurate for most folks. I have a GF/AP (depending on who you talk to) and I couldn't use the shoulders, biceps, or forearms because of my size.I'm using my FX parts for those. I'm 6-00 235 lbs. I barely made it, I didnt have to shim anything, except for the FX biceps. I used the butt joint/ front strip method for the legs and fudged the front strip from 7/8" to 1 1/4" to allow for extra size. Here's a pic. You would just need to be careful with assembly. watch the space between the chest and AB plate. You could probably fudge a little on the legs by mounting a smidge lower and mounting the power packs on the leg a little lower, you can tweak it a little. My build is better for JAngo, but I really like stormtroopers.
This is mine. 6-00 235 lbs.
