Tubular K frames

Hi everyone, I know there's been a lot of discussion past /present on this forum and others about tubular suspension. Right now I'm considering a tubular K frame on my small block Mopar. I was looking at QA1 and AJE Suspensions. Older forums have bashed both companies for bad welds and poor design. Has anyone lately used one of these companies and would like to commit? My car is only used on the street and at this time plan on using my restored/rebuilt upper control arms and restored/rebuilt/reinforced lower control arms.

Thanks in advance for your help,
