yeah, go to Barnacle Bill's website, he made my 1pc suit because I've got longer arms and broader shoulders than your average 6'2" body, and I had to have the suit made. Mine ended up running just under $1400 and I got the speed hump and my name on the back and everything.
It's your custom suit, I'm sure you can pick whatever armor you want and send it to them to put in your suit. If they won't listen to you, go somewhere else. Next time I get a suit made I think I'll get some T-pro stuff put in. BB has a great reputation on the WERA boards, and those guys crash a lot. I forgot to mention Bates, just to further confuse you.
