Need advise on Sub frame connectors

Completed installation of USCT frame connectors about a month ago. They fit well with only a little trimming depending on how precise a fit is desired. I would think that connectors continuously or intermittently welded to the floor pan would provide a far more rigid chassis than connectors welded front and back only. Glad mine was on a rotisserie for welding.
Yeah... i did mine on my back on the garage floor... it sucked a bit :) Not super happy with my welds but they will hold... i have a bad habit of setting up the welder and if it's not right.. just keep going instead of actually fix it. Not too bad just not what i would like.
