First, I'd like to say that this is a really really constructive discussion, really liked going through it.
Now, that being said, I'd just like to point out that a lot of time, I read that people over 6' can't go other than FX or should get the FX because of the size being bigger in proportion. Yes it's true, the kit is made bigger BUT IMO, it has nothing to do with height (look at me, I'm 6'3'' and been told (to my surprise) that I was looking good in my armor. Everything has to do with body proportions or weight. Forget height, I'm sure some people got discouraged by the fact that they were over 6' and went the FX way just because they read everywhere that the FX was pretty much the best option. While in fact, it has all to do with weight and body proportion.
I guess I'm lucky enough to be at 6'3 190lbs and looking good in my AP kit. I actually started a thread to get any feedback on things I should look into to make the fitting better since I'm a newb to all this too
Cheers
