For anybody wanting to add this lift to their training. Titan Fitness has a good deal on 3″ barbells that appear to meet the USAWA standard. $120 and free shipping for the Round Grip String Bar.
Titan has some great deals. I bought one of their 2.5″ rolling handles around 5 years ago and it is a tank. Spins freely still, even with it being stored in the garage with no heating or cooling. At the time, I think it cost $50 shipped. The steel alone is probably worth that.
