I had a set of Nagisa braces but sold them before even opening the box. A few of the welds I've seen on the RP braces looked terrible. I'm sure they held up fine and were plenty strong but when your paying a few hundred bucks to weld up a couple pieces of tube stock I expect a little more.
I ask because I am now planning on buying another set and deciding whether to just order the Nagisa's again or pick up a used set of RP's.
