I don't think so...what is a DJ and XC bike?
Sorry, I'm just a clueless commuter on a Cannondale.
I would tend to want to build a bike with round to oval tubing. When you add the corners things get strange in torsion. I can think of no benefit to using square tubing on a bike.
Also, when it comes to manufacturing, round is the easiest to produce.
Those square hole drills are expensive!
