Nice work. Bumper looks great and less bulky than an ARB. I prefer the bull bar because I wanted front end protection (and God knows having been in a couple of accidents they /do/ the job of preventing damage to the hood, grill and radiator).
For reference the standard issue ARB for my '91 IFS was about 80 lbs before putting a winch in it, the 140 lbs is I believe a fully loaded ARB with the winch. That's at least about what mine weights with an XD9000 and synthetic rope. Since you've eliminated the top hoops you've got the equivalent steel in the bracing, so it should be uber substantial.
