You brought up DOM tubing, problem is, 90% of people who use MS don't use DOM, they use cheap, welded seam MS. A well built DOM cage is as strong as anything else and DOM costs nearly the same as Moly. I personally used DOM on all my MS cages, but when I got to the point that I no longer MIG welded any cage, regardless of material, it made no sense to not use Moly. Makes the car lighter and worth more for resale. I don't care what the cert is, a Moly car will always bring more. I would not put MS in a new car period, but that's just me.
