About fullbodyarmors I see a lot of negative comments (and some positive ones, but mostly negative) but they work with plastic I believe and not foam, so that is a plus.
I'll go through my thought process I went through and why I ultimately decided to buy a buyfullbodyarmors(BFBA) suite.
A little over a year ago I decided I wanted to have an Iron Man suite. I had a 3d printer and the sky was the limit, so started searching for free files online. I came across some, and started printed. The ultimate quality of what I could make vs what I wanted just wasn't there, so I gave up. About 3 months ago I started my search again, and came across BFBA. I googled reviews and came across SuperDave's videos from 2015. I wasn't impressed and looked elsewhere. After another month of research/time I came to the conclusion that I wanted something that I didn't want to worry about lasting. I'm not the skinniest of fellas, though not heavy either (Think stocky), and I feared foam armor would just accentuate that, so I didn't want to go the route of foam. Through
Wannabe's thread on here, I wound up buying some 3d .stl files and started printing. I loved the quality of the files, but the time it took for me (with little to no skill) was more than my wife would put up with. I also realized that even just the arm was heavy, I couldn't imagine how much a full suite was going to weigh. I also saw reviews about the amazing work
Masked Rider was doing on his mark 42/43 run here on therpf.
I wound up in a discussion with an owner of one of Masked Rider's earlier suites who told me how amazing they are, but they are also fiberglass and heavy. He was only able to wear his suit for a couple hours before needing a break. Humm... I want to be a walking badass all day, not just 1 hour.
So, here's what I did, with the knowledge I had at the time:
Ultimately I decided I wanted a Masked Rider suite. I know, I know, not the highest score but the Quality of it outweighed everything else. Unfortunately he has limited spots on his run which has been going on for almost 2 years now. I sent a message and posted on the thread, and didn't get anything response. So I settled on the Armor Features being my next priority and went with BFBA, and put in the down payment ~ 2 weeks ago. They were running a deal with free shipping through the end of October(~$300 in savings) plus a kind soul here PMed me a discount code (3%) so that pushed me over the edge. The DAY after I put in my down payment I got a message from Masked Rider saying we could work something out. <sigh>.
Anyway, there's the saga of my purchasing BFBA... Over 1 year in the making.
Advice given to me: One thing I can say for sure is that any suit you get will need modding. Some quite extensively.
Your suit will require maintenance and TLC. In the end, YOU need to be happy with what YOU'VE purchased. As long as you're happy, who cares what anyone else thinks!

(I had attached a pic of my 3D printed arm and decided not to post it, now I can't figure out how to remove the attached thumbnail

oh well... )
